For this darling skirt and purse set, I used a washable yarn, but many other yarns would work really well. I used 2 colors, but this project would be beautiful in many colors- even made from leftover yarn. The purse is one size. However, the skirt size can be adjusted by adding stitches to the waistline (CO) or by adding a ruffle more. The size is easy to adjust. As written, this skirt will fit toddler sizes 3-5. The main portion is knitted while the edges are finished by single crochet.
