This year for Valentine's Day I wanted to make my daughter a shirt. I wanted to applique a heart on to a plain shirt, but wanted something with a little more pizazz. I found a shirt online that used fabric flowers and shaped them into a heart. Pretty cute.
All you need to do is make a paper template and cut out the knit flowers. I sewed the flowers on to the shirt by hand, but I'm sure you could use a machine as well.
