This "Praha Drinking Team" sweatshirt was too precious to give away and too, um, 80's to wear. So I made it into a kids' vest and a pair of sweatpants.
For the vest, I used Kwik Sew 2911 (again)-- this time sized 3T. It was really easy. I used fold over elastic (aka FOE) for the armholes and bottom. I made sure to line it up so that the existing collar would be where the collar was meant to go, so I didn't have to make one. And yes, the zipper has a heart as the pull-toggle. Love it!
The pants were made from the arms. I cut off the arms and lined up my favorite pants pattern onto them so I could figure out where to cut the crotch out. You could just as easily do this with a pair of pants that fits your child. There wasn't enough fabric left over to make the standard waist that I have been doing on all his pants, so I used FOE. I am happy with these, except that they taper inwards at the ankle a bit more than I like/ am used to. They are fine.
