I've been using a mini quilt I made over a year ago as a table topper on my night-table. The other day I tried to slide it and it was stuck. When I peeled it up, it appeared to have adhesive behind it, which now stuck to the wooden table, removing some of the finish. The spot was under a leak-proof oil diffuser, so I think it may have been the pressure of the weight of it (not too heavy) that may have caused the adhesive to squeeze out. Has anyone else experienced anything like this?

I did spill some water several months ago, but I immediately removed the topper and dried everything before putting it back.

Now I'm afraid to use spray adhesive on toppers, placemats, etc.
