So i am heat embossing a desgn on my pocketfold invitations (metallic)
for some reason, on most of them, the embossing is slipping off the invitation!! which means now i have to buy more pocketfolds

(what a waste of money)
i have made at least 100 invitations that havent peeled off yet.... is there ANYTHING i can spray on or paint on or anything too keep the design from coming off! im worried they slowly might stay coming off in time
(my wedding is in sept)
please help!!
(ps... im using the correct heating tool, and the ink is for embossing-it might just be the paper?)
