Having an inspired week end due to a sale and new hearts; I am purchasing more ribbon from a great supplier on Etsy. If you are very curious on where to get your own silk ribbon, I highly suggest purchasing ribbon from http://www.etsy.com/shop/SilkStudio
Silk Studio has fast shipping, fair prices and I love the variegated colors of hand dyed ribbon.
I also purchase some lots of specific colors off of Ebay. Searching Ebay can yield some interesting colors as suppliers make different lot batches.
