Candy Cane Holiday Wreath- This is probably the easiest idea to have your kids do. The styrofoam ring can be found in the craft section/store, yarn and any decorations you like to add. Wrap the yarn and tie off. Use yarn to tie the decorations on also. No gluing necessary. Instead of yarn you could use strips of wrapping paper and tape it around the ring.
Idea to make it mine....in laundry room, with threaded needles in hearts, and as buttons get found in there pinned to the hearts till needed...maybe fill hearts with lavender, and use laundry room quote. Use single lost socks in the mix too, maybe cut into ribbon as the bows, or sewn into the hearts...
