I'm a huge fan of the Dollar Tree just a few blocks from my house in Vista Village shopping center here in Boise, especially around the holidays. Their décor is killer, and so much fun to be creative with without costing much at all.
Last year I saw (too late) these large felt skulls, probably 18" tall by 12" wide in both white and black for a dollar a piece. By the time I thought about crafting them up to make darling Dia de los Muertos skulls and went back to the store, they were all snatched up.
This year I bought three, one each for Lucy, Alice and I to try our hand at. While I originally thought I'd get out my embroidery thread and needles for some cute stitching, I quickly changed my mind because, um, crafting with kids is sometimes hard enough without making it harder (am I right or am I right?). A faster, easier method of getting the same colorful details as thread? Brightly colored Sharpies.
Pull up some sugar skull and face painting images of Day of the Dead from the Internets for inspiration. Add in a few tubes of glitter glue, sequins and leftover Mardi Gras mask making feathers. Voila! Cutest decorations to grace our front window during any Halloween season we've had. (Pro Tip: the plastic hanging hook that the price tag was attached to? Don't rip it off. Use it to hang your skulls on a tiny suction cup hook on your window!) I even ran back to the Dollar Tree to snatch up three of the black skulls to craft up next year before they ran out. Again.
