Cookie mix sounds fab, love the layering idea. Blathers - christmas tree handprint - fantastic! Think that's my cards sorted, although would def need to scan handprint in rather than trying to print lots! Calendar good idea too, like it, like it!
Having trawled the craft threads, here is my list so far:
Plain white mugs (Asda!) with baby hand prints - marabu ceramic paint is water based and bakes on in the oven, dishwasher safe.
Truffles in nice boxes? Make boxes???
Name bunting for kids - using pinking shears so no hemming, bias binding ironed in half for easy placement, and that iron on stuff to attach the letters
sock monkeys - no idea how to make these but sounds fun! more research needed.
christmas decorations
Flower brooches/clips - done before for my niece so will find some tutorials online
Candles in teacups and saucers from charity shops - as per MN thread!
Tile coasters with hand prints (cork feet from wilkos apparently)
Painted wellies????
