Attaching Patterns To Wood
Here's a tip for the new scrollers out there. When attaching you pattern, first use clear packing or blue painters tape on the wood. Make sure you don't overlap the layers of tape. This will ensure your pattern will lay flat on the wood. Then apply your adhesive to the back of the pattern. I've been using Elmers Craft Bond multi-purpose adhesive for a few years now with great results. After spraying your pattern, let it sit about a minute so it gets tacky. Apply your pattern and cut away. When you are finished cutting, you can just peel the tape off with the pattern.
If your making puzzles and you want a permanent bond, spray the wood and the back of the pattern (no tape). Immediately apply the pattern to the wood. Smooth it out and you will have a permanent bond. If you want a protective finish on your puzzle, let the adhesive sit for about an hour (to set). Apply two light coats of either puzzle saver or Modge Podge. Wait for the first coat to dry before applying the second coat. This is a water based product and could lift the pattern from the wood. Once dried you can cut your puzzle.
