I started with a long sleeve black shirt and two pairs of striped leggings from Target. My niece is currently wearing size 18 mo. but I also bought a size 4T in the leggings as well.
Because this is a stretchy knit material I wanted to be sure to use Heat-n-Bond Lite to secure my fabric while stitching. Knit is notorious for rolling up and puckering...which can be nice for a raggy finish, but not when satin stitching is involved!
I love having some of the pants pattern included in the top and now I am tempted to go buy a pair of 2T leggings for next year as I have enough fabric left from the 4T pants to make another cute shirt next year!
Here are some of my favorite spots to look for cute and affordable bottoms to purchase in duplicate: Old Navy, Target, Gymboree, Crazy 8. Any other recommendations?
