I love it when my sportswear jackets or hoodies have a thumbhole! I love that it allows you to keep your hand warm in the sleeves! And they’re so easy to make. I’ll show you how!
Watch the video for a quick review of the steps, or read on for more details!
First of all, the assembly that I propose here only works with knit ribbing cuffs, folded and mounted at the end of the sleeves. For sleeves finished with a single hem, you’ll have to create a hole and finish it with a bias for example, or find another technique.
If you want to integrate a thumbhole at the end of your sleeve, you will surely want the finished sleeve to be a little longer, to fall on the hand. So plan to extend the sleeve by 1 to 2 cm (1/4’’ to 1/2’’) (before applying the wrist). I’ll also advise to increase the height of the knit wristbands by a few centimeters so that they are more covering than in the photos above. The table below gives the approximate heights to be taken into account for both wrist bands (2 to 6 years, 8 to 12 years, 14y, 16y and adult sizes).
Regarding cuff length, refer to the pattern you are using. If you want to add cuffs on a pattern that does not provide for them, measure circumference of closed sleeve. If elasticity of your ribbing is more than 50%, cuff length will be equal to 80% of sleeve circumference. For 50% or less elasticity ribbing, cuff length will be 90% of sleeve circumference.
