Whether or not an empty wine bottle is transparent, it can make a great bottle light! Mark where you want the holes to be with some masking tape, drill, rinse the bottle, then stuff Christmas lights through the holes you drilled. (via Wit and Whistle)
I love this SUPER simple tutorial for Borax crystal icicle ornaments! It uses just 2 ingredients, has few steps, and they aren't fragile at all. The best part - it's WAY cheaper than store-bought and they're a fun experiment to try with kids.
