We did this last year for my granddaughters Girl Scout troop. All the material was precut, and we had several sewing machines available, and several adults to assist. Some of the girls were actually very nervous around the sewing machines. Some were sewing like pros. They made small lap quilts for the local old folks home, and after they had sewn them all together, Moms did the tying. They all had a good time, just make it simple for them.
