i have redone the foundation multiple times and there is no way it measures 41". i am using the same size hook, same weight yarn, and my tension is like yours. i see you say to keep adding until you get to 41", so should the pattern actually be keep making chains until it reached 41"? i also started the rows and they look nothing like yours. i am a beginner and thought this would be a great pattern to start with but i am confused and discouraged :(


Monday 31st of January 2022

Something is not adding up. I am making a L-XL size. Using a 3 weighted yarn with a 4 mm hook and loose tension. However 150+2 chain is no where near 41” long. It sits at about 38.5” long. So now I either have to have a likely too short cardigan or undo almost HALF and restart….what am I missing here….?


Tuesday 1st of February 2022

Hi christina, maybe u couldgo up for one siz e for crochet hook for 5.00 mm. Let me know if it help.


Sunday 8th of August 2021

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


Monday 9th of August 2021

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.

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


Saturday 13th of February 2021

Hi Jeanette, make it longer add more row.


Monday 4th of January 2021

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?


Tuesday 5th of January 2021

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.
