I think about wool a lot. Probably too much. It's even stretched over to sheep. They are so cute. I even have a few sheep home decor items that I've picked up at various places. I don't like the cutesy sheep with the faces painted or stitched on, more prim looking without a face. I like my dolls the same way, like Amish style or the Willow Tree Angels. Anyway, back to wool.
Purists will say only 100% wool will do. I do like it, though of course it is more expensive. I've found wool blend felt to be a nice compromise. Definitely a huge improvement from the craft store felt. It's not an acrylic blend either; I believe it's rayon. Of course you don't get the wonderful mottling and textures with wool blend felt though that you get with 100% wool. How I do love a beautifully mottled piece of wool!
I'm playing around today. It's rainy and gray out, so what else is a girl to do. I took some of my wool blend felt and, well, felted it some more. It made it much thicker and gave it a slightly nubby texture. I'm going to stitch up a small candle mat and see what happens. I already like the texture. It's thicker and almost gives the appearance of 100% wool. Of course it shrinks quite a bit, but still a more economical alternative to 100% wool.
I do think that one day I will switch over to 100% wool, but I'm curious to see what my crafting friends think.
I know for rug hooking only 100% wool will do, but what is your preference? Does it matter to you what the material is made out of when purchasing an item?
