Thanks
Yes. I use spray adhesive and I spray both the wood and the back of the picture.
I am still experimenting to find stronger and better ways but in general spray adhesive works ok for me.
I put the pattern on a dollar tree poster board and tape it over the picture.
There is a bunch of little gotchas I learned after doing so many puzzles.. One is taping rows back together as you go.
BTW,
I have found that the FD PSR 2/0 blade cuts best giving excellent control. I tried the MG 2/0 but immediately went back to the FD PSR.
I think that if you try to get too many cuts with the same blade, the crisp picture edge suffers slightly.
