This is actually two great links in one . (Actually am putting it here so I can find it myself...I have about 1,000 book marker/favorites now and can't seem to keep track of all of them) .
The original link is to "Craft Gossip", which has great craft tutorials and links to other crafters blogs and this particular article has a link to the felter..."Gourmet-Felted" from Etsy, who does some of the most amazing animal felts and has some great info about how to felt on their blog . I just found some info there about using wire armatures that I am interested in trying .
So, if you need to spend some more time on-line, check out these cool web sites .
