The following fabric you see below were part of previous group buys, have been discontinued, or were a limited run in the first place. The Challenge Sailcloth fabrics and the colour gridstop were a part of group buys I hosted in an attempt to make certain types of fabric more available at times when other suppliers were not carrying them.
By bringing in variety, I helped people like you get access to a wide range of fabric with no factory minimums. The downside is this variety is not sustainable for the size of my current operation and therefore not stuff I can carry long term.
