  1. Fayleen Collamore says

    I am guessing that may be a typo on the length? Says 297 inches, should it be around 29 inches as in your chunky cardigan? Love the pattern and especially that shade of blue!

  2. Super cute!! It says to go 41 inches wide and 297 inches long? Am I reading that right??

  3. Thanks you Kate for spot the typo mistake it 27 inches long.

  4. Thank Fayleen it a typo mistake thank you for spot on it. it was 27 inches long. I just fixed it in the post now.

  5. If you use 7-8 skeins what size do you think that is? I would need XL to 2X.

  6. Hi Kimberly, 7-8 skein will be fit to size xl if you need to make it to size 2xl I calculate will be about 10 skein.

  7. Sharon Williams says

    Hi I really love the blue lagoon cardigan it is so very pretty, I have not been able to print the pattern off, is there anything you can do to help me.

  8. Hi Sharon, I will add the print friendly version for this pattern soon.

  9. Melissa Mosley says

    Lovely cardigan. In your pattern, what size does it fit?

  10. Melissa Mosley says

    Never mind. I see it fits from small to XL. Thanks! How much should I increase the foundation row to make a 2X or 3X?

  11. Hi Melisa,
    The foundation chain is 160 for 2 xl and 180 for 3xl.

  12. How many foundation chains would you use for a small?

  13. Hi Rachel, for small would be 120+2=122 chains

  14. Melissa Murray says

    Hi! What would the stitch count be after each row? I’m not sure if my tension is off or perhaps I’m adding extra stitches by mistake. Thank you!!

  15. HI Melissa, the number of the stitches count is not an issue. no worry if your add more stitch or less because we are making a kind of a blanket and transform them to cardigan anyway the nature of blanket cardigan if u off by 1 or 2 inch will be fine and they will come out with the good result and pretty. Hope this help ^^. if you finished one would love to see your creation tag me or Instagram.

  16. Sharon Earyes says

    I’m confused…it says that it should be 41 inches wide but 140 chains is only 38 inches. Will I gain those few inches somewhere?

  17. HI Sharon, my chain is quite loose so 140 chain is around 41 inch. so if your 140 chain is measure only 38 inch the solution is add more chain to get around 40 inch, your one maybe make 152 chain( multiple of 3+2) , or u can go for it for 140 chain at 38 inch but the cardigan will be a little tiny bit smaller which is not much different for the size. hope this help, Let me know how it’s go for u.

  18. BeagleMom says

    awesome cardigan!!! very easy to follow pattern, and thank you, thank you, thank you for the photos!!! i can follow pics and charts so much better than written…..

  19. HI Beaglemom, I am so happy to hear that you like it ^^

  20. There are so many ads on this site that I could not find a way to print these directions….also, hard to tell which…the directions…or the ad

  21. Hi Faith, I have put the Ads on my site that way, because I need it to cover the cost of webhosting, supply on yarn, tool from the ads so I can keep providing free pattern and tutorial on my blog. Thanks you for understanding.

  22. Hi am almost finished this cardigan just at that last part where you hdc around the collar, I’m a little confused. Do I finish off after each row and re-attach yarn at the first stitch marker to start a new row?

  23. HI Carla, Donot finished off each row just chain1 and turn to the next row. hope this help, let’s me know if u have more question ^^.

  24. Perfect, thank you.

  25. How do you think this would look if crocheted in Acrylic yarn?

  26. Hi Susan,
    It’s would be perfect for acrylic yarn. Will be very warm for winter.

  27. Hi Jane, For the collar are we working “in the round/square”? What I mean is, are we going around the side up the collar, back down the side across the bottom and back up the side? Or do we just do 6 inches at the bottom, finish off, then do 6 inches on one side finish, etc??? thanks

  28. HI Manon, about the collar I just do round the side u know just imagine it a square of the collar u did only round up except the bottom part.
    If you look at my pic I have put the stitch marker at the bottom part then u just crochet back and forward toward the stitch maker except the bottom part. Oh well I try my best but my English not so great I hope you got what I mean.

  29. Do you have a video of this pattern? I follow so much easier by watching it.

  30. HI Wendy, sorry I donot make the video tutorial this time.

  31. Hi again, I have a question regarding the next step after Step 2. When I did Step #1 again, it didn’t look like your pattern, so I just kept repeating Step 2, double crocheting 3x in each space. Will that work? If not, please clarify that step for me. I have a photo of what mine looks like but I’m not sure how to download it to this comment to show you.

  32. Hello, What does 3c mean in step 2? please

  33. HI Fanny, work 3dc mean work 3 double crochet all in the same space of the previous row.

  34. Mariluz seoane says

    I loved it. It´s so cute and lovely. I´ll make soon.

  35. Joanna Simmons says

    I made the base piece. And I honestly don’t like the way it fit but I feel like I can somehow make it work. Is there anyway to add a sleeve to it?

  36. HI Joanna, if you would like to add sleeve to it just simply crochet ribbing band and attached them to the armhole of the cardigan, you can see how to rochet ribbing band from my another crochet kimono cardigan.

  37. Hey I can’t wait to try this pattern, do you have this in kids also? Would love to make a matching pair for me and my 5yr. Thanks!

  38. HI Wanda, For smaller size You can decrease foundation chain to 60 +2= 62 chain That will be small enough for 5 year old or my tip is to chain the multiple number of 3+2 then use the foundation chain compare with her size of jacket.

  39. Debbie Hampton says

    What siz wheedle to you use? B seems small to me

  40. Hi debbie, In the pattern i use 2.5 mm hook but you can also got o to 3mm hook or bigger also just as long as you get the rectagle.

  41. I did 140 chains but it measured 25 inches rather than 41 inches so I added more 270 Chain using 2.5mm hook, I’m just wondering is the size of the hook?

  42. Linda Soderman says

    Directions say Repeat row 1and 2 until rectangle measures 41 inchsa. Is the correct?. The photos do not show repeating row 1 throughout the project.

  43. HI linda, yes repeat row1 and 2.

  44. Bonjour, il est magnifique, est ce possible d’avoir la traduction en français, SVP?

  45. Jennifer Morgan says

    I jsut got the pattern for this cardigan yesterday & fell in love with it. I had an understanding that weight 4 yarn could be used to make this. I have started making it in Lion Brand’s Cobblestone. I noticed that the holes are small & was wondering if it was a problem for me to use this yarn?

  46. Hi jennifer, it’s depend on the type of the yarn that ‘s would be fine if u happy with it but , if u want the hole bigger maybe u can go up to use bigger crochet hook will do.

  47. Lori Snyder says

    I just finished making this pattern and I LOVE LOVE LOVE IT!!!!!

  48. Hi Jane
    Could you please tell me were the printable pattern is for this please

  49. Thanks u so much Lori.

  50. Hi Tracey the pdf printable is in my etsy shop link is in the post thanks u.

  51. Barbara Patterson says

    I have some #2 cotton blend yarn. 52% Cotton, 48% Acrylic. Would this work for this? Or do you think I should work with 2 strands maybe?

  52. Marie-Anne Lebeau says

    URL address for your Etsy shop link please

  53. Hi Marie, i just fixed the link now u can go to my etsy.

  54. Hi Barbara, What yarn weight for your cotton blend.

  55. Hi!
    So I started making this lovely cardigan but since I am not american and have no idea what an inch is, I converted the inches in to centimeters. 41 inches = 104 cm but my 140 chain is only a bit over 50 cm which would be about 22 inches. is there any way you can help me?

  56. HI mia in the case u might have tight tension stitch no worry about it just add more chain so I calculate you need 258+2=260 chain you will get close to 41 inches this is for size small to medium,

    if you are large size from L to XL you might need 282+2= 284 chain.
    Please let me knowhow it go.

  57. Jeanette Medina says

    I would like to make this longer, how would I do that?

  58. Hi Jeanette, make it longer add more row.

  59. Your English seems fine to me. I didn’t ask the question but I do understand your answer.

  60. Thank u Connie

  61. Hi. Wondering if I can make this shorter. Too much around the butt lol. I am a size medium. Thank you.

  62. Hi Rhonda, yes you can make it shorter by start with 132+2=134 chain and the height of the rectangle u could go for 22 inch instead of 27 inch.
