We finally got out that bin of crayons and unwrapped them all, then tossed them into the trays.
We baked them in a 200 degree oven for about 15 minutes (maybe it was longer...I didn't really time it, just kept checking on them until they were melted) then let them cool and popped them out.
We packaged them up in individual bags and I cut decorative edging on cardstock for Ben to use for the header tags. He stamped each one and stapled them onto the individual bags to take to school next week. Valentines: done.
