For new stampers trying to make a priority list:
Really work on stocking your supplies (as hard as that is with so many wonderful stamp choices). A five-year veteran suggests:
Rubber craft scissors (nothing trims new stamps as well as SUs!
Work on amassing each color of cardstock and stamp pads (buy them in group colors to get a bit of a discount).
The eyelet tools
Each order get at least one set each of brads, eyelets, buttons, SU! ribbons.
Worst purchase: Color Chart Wheel....I've seen some wonderful color combinations in SUs! catalog, but when comparing it to the Color Wheel there is no rhyme or reason. It absolutely does not help in creating wonderful color combinations for those of us who are creativity-impaired.
