This would be a good DIY! Get plywood cut to order from your local hardware store. Mark the positions of the nails with something removable, like soap, fabric chalk or pencil. Then use the string of your choice to make a gorgeous sailboat.
Wrap some baker's twine or other string around a wooden block to create a graphic textured stamp. -can also use rubber bands- Stamp on inside of paper bags from grocery store or paper that comes in mailed packages, use as wrapping paper.
