Photo: GREAT DIY GIFT IDEA! Place marbles on a rimmed cookie sheet and bake at 325 to 350F for 20 minutes. Remove from oven and place marbles in ice water to make them crack on the inside. (Be smart and wear safety glasses during this step. Ive never had marbles shatter, but wearing glasses just seems like a good idea). :-) Use E6000 glue to attach marble to jewelry findings. You can find jewelry attachments at any craft store. Easy-peasy!
bird houses... DIY would be to cut sections of PVC pipe in the height you want for the bird house, drill or cut holes in the side as the "entry", hot glue rocks, or glass stones to the PVC pipe, attach a funnel to the top, could use a piece of tile or slate for the bottom....How cool and great kids project
