Tips:
This is the skirt I previously blogged about here that was too big for F. I decided that unpicking this would not be very enjoyable so what I did intstead was to cut the front of it from bottom hem to waist. I then added a contrasting fabric behind it and folded in the excess fabric to get the skirt to the correct size.
Next time:
This worked out ok because the skirt was too big and would not have been used if I hadn't fixed it, but for a better result it is probably better to sew the two pieces together before doing the upper and lower hem.
