This didn't work as planned. I was trying to make a skirt for Ella Bella. I used the directions here. The directions are very well written, but I severely underestimated the stretchiness of the sweater. I sewed it according to the directions first, but it was way to big in the waist. I took it in 6 inches and it's still too big... for BOTH my kids. So maybe third time is a charm?
It was really easy though, maybe 10 minutes to sew together... ummm... each time. I will try it again, just take into account the stretchiness of the fabric.
