Besides paper (and lots of it) I'd say a trimmer is a must have. Scissors will never be as precise, or as quick, as a trimmer in certain instances. Other items I reach for time and again are my cutting mat, my craft mat, brown ink, scissors, and my craft knife.
I've tried a few adhesives, from glue sticks in the beginning to my current love - the ATG gun, and I've come to the realisation that you need a few different types of adhesives to scrap efficiently. You need a tape runner for everyday use,
Glue Dots for quickie sticking, and a liquid for those it just won't stick any other way moments. My personal favourites are the ATG gun, the "sticks to everything"
Glue Dots , and
Tombo w Mono.
I love my Cutterpede for the decorative blades I can use to make pretty borders, and my new Rock Paper Trimmer for its accuracy. I really like all the
Fiskars products I own, so if this trimmer is still available once I've completed my use-up-the-stash goal for this month I will definitely be purchasing one. It will be a gift for my cousin who has recently expressed an interest in learning to scrap.
