Cheap Homemade Toy Blocks for Christmas

I make blocks for my three grandsons by going to the cutoff bin in my local Home Depot store. They have lots of short pieces of wood that can be cut into blocks. I sand them while watching TV. I round the edges, apply stain and then polyurethane them. I then get one of those handy paint buckets to store them in. My grandsons love to build with these and can even take them outside to their sand box if they want. They are pretty durable.
