Kids can string along a good idea, by creating three 3D yarn pictures. Begin by sticking pins (170 of them) into an 8½˝ square foam canvas (3 of them) – then start crisscrossing colorful string (60 yards of it), until your design takes shape. Follow templates for a heart, peace sign or big "Hi" – or imagine your own design. No hammers or nails, just loads of stringy fun! From Ann Williams Group, for ages 10 yrs-teen.
