Alphabet Pebbles: What a marvelous little rainy day project! What a great shower gift for baby tied up in a little baskets or made into magnets. Great as teacher gifts, Trim out a cute mirror or bulletine board for a child's room....endless ideas! Puzzle glue will shine them up and protect from chipping.
Pebble Rock Art. This costs $145 on Etsy & is adorable but I thought a fun project with kids could bring a very cute, frame-able end result.
