Shall you are looking for felt suppliers on the net, you can click one of the links below. I guaranteed you that all of 'em will give you a superb service! I just put a few blogshop first, the one that are currently actively operating (coz I always see 'em in my Top 10 Crafts Shops Updates). However, you can expand the list (click Show All) to see more suppliers :-)
Besides selling the felt fabrics, those blogshops also sells variety of craft supplies, such as buttons (for button, I normally go to Button Planet Enterprise), keyrings, split rings, threads, foam sheet, etc.
I'll try to update the list from time to time! Happy Crafting!!! :D
