The suggested time below may vary with iron, paper and operator.
Most household irons are steam irons. DO NOT USE STEAM.
Preheat iron on highest setting (cotton) for 8 minutes.
Ironing surface: Place puzzle on a hard surface (such as Formica or glass).
Cut away excess (unprinted) portion of the transfer paper. Image should cover entire jigsaw puzzle.
Place transfer image face down on jigsaw puzzle. Place blank paper or silicone sheet on top of transfer.
Starting from one edge, push iron slowly along LONG side of puzzle and then with quick circles, iron all of puzzle for 15-30 seconds using firm body pressure while pressing down iron. Be certain iron overlaps ALL edges of transfer.
Immediately place iron aside. Allow puzzle to cool for 25-30 seconds. Beginning in one corner, peel transfer evenly across top of puzzle using firm, steady pressure. PEEL WHILE COLD.
Wait 10-15 seconds after you peel transfer paper and then carefully SNAP apart each individual puzzle piece.
*not recommended for puzzles larger than 7.5 x 9.5
