Thanks for all the great ideas. Found a pattern I like to, and it seems pretty simple. I'll talk to my friend and tell her what I've learned here to see what she wants me to do.
I don't think the coasters will get much use, more of a decretive thing being it's from their own dog, but I'll pass on the concerns.
My friend who thought me to spin uses dog fur in many items, however, it is blended with other animals, such as sheep, but says it always works well for her. She even has a coat spun and knitted from her own dog, blended with wool.
