Why are my diamond art drills falling off?

Most often they were not pressed firmly enough into the glue, or the area picked up dust while left uncovered for a long time. Pictures that are rolled or folded after drilling also lose drills along the edges.

Press each finished area with a roller, put the film back between sessions and store the canvas flat. For a drill that popped off a spot with no tack left, a tiny dot of clear glue is enough. Once finished, a sealer or a glazed frame keeps them in place for good.
