Using some paper, print or draw your layout. Tip: make the hole center marks as small as possible but still visible. This helps reduce positional errors.
Use the Krylon® Easy-Tack™ glue pictured below (or a similar adhesive) to attach the paper to the piece of material that is being worked. This glue is a repositionable adhesive and makes this process simple and clean with no mess. Be sure you let the glue dry on the paper first before placing it on the material.
Apply paper with dried glue to the piece being worked. Use a center punch to mark the center of each hole. This will help keep your drill or cutter from drifting. Now drill or cut your holes.
See how the material is not damaged by the drilling. The paper protects the surface and is easily removable after completion.
