Well I would suggest maybe buying the little girl without an AG a springfield collection doll with a 50% off coupon that she could take home if the crafts you are making are for the doll, if you use the coupon it would be pretty cheap. I also know at AC Moore and Michaels they sell the premade ceramic things you can paint. They have a varity of things and quite a few boy things.My DD had her party this year at "plaster fun time" and 4 boys from her class came they really enjoyed painting the ceramics. I still think boys at 10 enjoy arts and crafts type projects. I know recently they had wooden birdhouses that could be painted at Michaels, I think boys would really enjoy making those too!! I really dont think you need to do two seperate parties it sounds like it would be fun if you have the arts and crafts. And as suggested if all else fails have DH do something a bit different with the boys. Hope you DD has a great bday!!
