HI, I have a ds10 who is a crafter. I by-pass the kids dept and go straight to the 'adult' area. Basically anything I do he can do.
What types of crafts does your DD like to do? I've found a well stocked craft box with basics goes further and is more cost effective in the long run then the 'craft kits'.
For example I have tons of those little bottles of paints. Generally under $1 on sale, I have glitter, glitter paint, foam, foamies- you get the picture and then DS can pick out a wooden box, crate, letters etc and then he can sand the edges, paint it, seal it, and embelish it. The project works out soooo much better then buying a pre-fab kit!
DS also likes to use yarn and crochet/knifty knitter. We have Knifty Knitters and he just uses those and crochet hooks. He has made some pretty neat stuff. No need for kits. I will buy latch hook kits.
DS doesnt make jewlerly but I do, again no kits but I have a wide variety of beads, metal string, 'do-dads' and the internet to spark creativity.
Blank art canvas are cheap, you have paint, brushes and off she goes.
Something else we did was buy canvas bags, ribbon and 'sparklie stuff' and DS and I made embelished bags for grandma, auntie etc one year.
For fun he likes the color wonder products by crayola. (or he did, I found a bunch of it in the closet and he is using it up. DS hasn't asked for anymore) I've found that works the best and acutally does what its says its going to do!
