Please do check the national website for Quilts of Valor,
www.qovf.org. One way to save on postage is to locate your state's coordinator(s) and contact her as to how quilts can be delivered free. Some quilt stores may accept QOVs and deliver them to the coordinator. My state now has more than one coordinator. The nearest one happens to have a monthly sewing circle in a church near my daughter's home, so I visit my daughter that day and deliver my own QOVs directly to the coordinator (one very awesome person!). I also deliver QOVs and quilt tops for my fellow guild members.
Another way is to give a QOV directly to a veteran and report the donation to the website so that it can be included in the official count, which is now well over 100,000!
You can find this information and more by looking at the left side of the main screen and clicking on the appropriate field.
Hope this helps.
