We are often asked what kind of glue do we use for our craft projects. We always say on the packaging 'a quick-drying, craft glue' but to let you into a little secret we find UHU brand is the best. It's great for most materials and holds fast forever. If you can get hold of some you'll find some tasks much easier particularly paper projects. Let us know how you get on.
When creating your foam picture, check which pieces to stick first. Always stick pieces that are shown at the back of your design, then layer it until you finish. If you get it wrong, it's okay, because you can peel off the foam and try again:)
