Operation Christmas Child shoe boxes. I also inherited some wonderful Noah's ark fabric that matched the theme of the puzzles. Well, with my daughter's help we have finished the puzzle project and have 23 ready to add to our 2 to 4 year old boxes at zero cost.
We've included a card stock image of the completed puzzle (my daughter scanned the puzzles and put two images on one sheet--cut in half they fit perfectly in the bags). The cardboard is nice and sturdy and works just fine being built without the cardboard frame.
By using the donated puzzles, inherited fabric and scraps of bias tape and yarn from other projects we have been able to provide 23 little ones with a special gift. This is something I want to get better at: using what I have to make nice gifts for the children so I can pack even more boxes.
