These are UNFINISHED, BLANK, Puzzles. Our Puzzle Shapes FIT precise and connect together easily, unlike some of our competitors! So if you are wanting to connect your Puzzle Pieces after painting and decorating them, you can definitely do that. These make a cool collage once decorated, connected and hung on the wall. NOTE - If you are wanting to hang this on a wall, we recommend using Command Strips. Make sure to purchase the strips that can hold a lot of weight. Command Strips come in a variety of pounds. So make sure to get the appropriate ones for your project. OR just use the "ole screw it into the wall" technique :) Why do command strips fail? You don't prepare the surface correctly! Strips work best on clean, smooth surfaces, so wipe the wall with isopropyl rubbing alcohol (methylated spirits) first. This will ensure your strip bonds properly with the wall. Avoid using other surface sprays or cleaning wipes, which may leave a slippery residue. Our puzzles will help make your projects easier and look nicer with our sturdy, high quality cutouts. We like creating custom orders through email too, so if you have another size or project in mind, we can help with that. You can send us a message to support@kraftysupply.com
