Our local thrift store often has "bag sales". I love to take advantage of this great deal and usually find some great stuff. During the last bag sale I found a really cute purple outfit in great shape for Hannah. I also found a remnant of green interlock knit. Even with little girls, I prefer the "leggings are not pants" viewpoint on modesty, so I knew that I needed to add a skirt to the purple pants:
I used the green interlock knit to make a half circle skirt and sewed it to the pants. Super fast and easy! Because it was a knit fabric I didn't bother with any hemming. I just cut and used a zig-zag stitch to sew the back seam and sewed it to the waistband with another zig-zag stitch. I took about a half hour total...and that included looking up a half circle skirt tutorial (I used this one).
Cute, easy, fun...and a happy kid!
