A good assortment of singles, and "sets" would be good. And, different sizes of "sets" would be neat, too. You know-depending on whether someone wanted to make earrings (symmetrical or asymetrical), bracelets, necklaces (with varying numbers of spacers/focal beads), mini-sets for making earrings with or without matching pendant-necklaces, or even sets of 3/5/7 matching beads (matching colors/patterns) for keychains,cellphone charms, purse swags, fan/lamp pulls,etc. My sister and I went to the Canadian Oasis Bead Show here in Calgary in April. We had a ball sorting through baskets of lampworked beads trying to find ones with similar colors/designs, etc.
