A few weeks ago, I offered a Ribbon Share from Stampin' Up! that included 15 different colors and types of ribbon. This is an excellent way to get a nice variety without having to buy a full spool of each one.
Each spool was divided into 5 equal shares and I wrapped them around a piece of white cardboard that I had put through an embossing folder and then stamped on the top. The linen thread at the top is part of the share too.
