Hi Russ Cut out your Heart pat. last night and took an even thriftier approach. I used no tape, no mineral sprites, and VERY little spray adhesive. I even let the adhesive dry to the point it almost wouldn't stick to my fingers. After cutting, the pat. pulled right up. PS, I have a friend who almost always finishes his cuttings with Watco Danish Oil. He doesn't even attempt removing his patterns. He just dips his ornaments in a pan of the oil and it loosens his pattern at the same time. Might be a little impractical for larger pieces but your foam brush with Danish Oil might kill two birds at one time.
Assuming one wanted the danish Oil finish.
