Church Anniversary - maybe Plain CC in Scrabble tiles, with years below? DIY Baby Craft Ideas - First Christmas Ornament made from Scrabble Letters and blanks with the date painted on it and ribbon. Simple and cute.
For the Christmas tree- Glue 2 mini mirror tiles back to back and insert a silver metallic cord for hanging. Fill the insides of the tree with these after putting on the lights, but before putting on the ornaments. The sparkle will be tripled.
