I think I may have found a good combination of paper cutter and adhesive.
Making Memories Paper Trimmer: This trimmer has a similar concept to the Rotatrim or other professional paper cutters that you would find at a Fedex Kinko’s or photo lab. It has a rotating blade that slices along the edge of the cutter (kind of like scissors blades slicing against each other), so it is a bit different than the typical scrapbook style trimmers on the market that slice along a groove. This process allows the blade to stay much sharper, which results in clean cuts even after a lot of use. I really like that the 12×12″ surface is foldable, which makes it very stable but also portable. Overall, I am highly impressed with this trimmer.
Scotch ATG (Adhesive Tape Gun): I found a recommendation for trying the ATG on a scrapbooking forum, and I’m so glad I did! It is pretty hard to compare this amazing product with any retail adhesive products. This is a tool made for professional framers (portrait photos or art prints or canvas, multiple mattes, custom cut frames, etc.), and it is a bit big and industrial in appearance; however, the benefits far outweigh any drawbacks. The refills I bought are 60 yards vs. 10-15 yards at around the same price. Good for costs as well as efficiency, since I don’t have to switch refills as often. Plus, the adhesive lasts much longer. Some of the invites I put together for my sample book had already started coming apart, but the ones using ATG are still perfect. 5 stars, 2 thumbs up, wonderful product!
