Did you see that See Kate Sew has designed and released a bunch of mini-me versions of her Women's patterns for girls?!? I was able to test the mini Zippy Top pattern - the Little Zippy.
It's a quick pattern sewn in woven fabric (knit would work too). The pattern doesn't require much fabric and only a small zipper for the back.
This top was a joy to sew because we actually went to Joann Fabrics together and picked out the fabric (swiss dot cotton floral) and zipper color. She's was happy to get it so quickly. Most times she'll request an item, I'll buy the fabric, and then never get around to finishing up the project. This was less than an hour (maybe less than a half?) cut to finish.
I think the only change to the final pattern from my test version is that the final pattern is a little longer. It's great having a quick pattern that I can make cute shirts with my scrap fabric. And since it's a basic pattern, I can see a lot of creative possibilities in making it my own (color blocking? pockets? stenciled?). More about the pattern can be viewed here!
