Julienm1, I'm with WMUTeach on this, and would like to add that buying basic black doesn't really feel much like adding to stash because something like that might allow you to clear out some of the less versatile fabrics you have on hand. I'm learning this lesson myself - I have lots and lots of prints and patterned fabric but not always the solids and blenders to tie them together effectively so am now actively looking for those types of fabric. Enjoy your purchase and don't give up your seat on the wagon! :-)
P.S. $4.99/yard? I can't get fabric at thrift stores for that price... drooling!
