My mom was at a Walmart Fabric Dept yesterday and the manager there told her about an online petition to save the Walmart fabric dept. I found the link online here. It now has over 33,000 signatures. From what I have read there and a couple other places, them closing it is a huge deal in some of the small market towns where there is no other place close to buy fabric.
I also read somewhere that written letters get a lot more weight then phone calls. May be worth the 37 cents or whatever the price of a stamp is now.
BTW, the one my mom was at told her they just got a year extension on staying open. That sounds like a good sign. Mainly because I may have found a good source of ripstop.
