1. Draw in seam allowances and hem allowances on the pattern.
2. Cut the cardigan along the side seams and up through the sleeves.
3. Fold the front of the cardigan on the center front (button placket) and line up the pattern along the fold. Line up the neckline of the pattern with the neckline of the cardigan.
*Make sure you check where you are cutting along the bottom. Don’t cut through a button or a buttonhole, but cut about an inch above or below to give some room for seam allowance.
4. Do the same for the back. You might have to play with the neckline a little bit to get it to fit.
5. Use the sleeve or sleeve band to cut the sleeves. I used the ribbing of the sleeves. I curved the ribbing and cut the sleeve band on a curve. (You can see in the second picture the curved sleeve band: one side is straight and one side is curved.)
6. Then I sewed it on just like a regular sleeve.
7. Cut off the ribbing including the button placket.
8. How wide your pattern is will determine how long the ribbing should be. I like my ribbing to be 75-85% shorter than the circumference to pull it in and make it look good. I ended up using the entire front section of the ribbing for this baby cardigan. I just sewed it together at the back and matched that center back seam to the center back of the cardigan. I also lined up the button plackets on the front.
9. Construct the cardigan as the pattern instructs.
