First, a disclaimer: I am a complete novice, and my only knowledge consists of what I have absorbed from the internet and various books.
I am in the planning process of a large-scale (year-long) project for school in which I purchase a sheep fleece, wash it, card it, spin it, dye it, weave it, and ultimately create a garment from it. I know there are a thousand details to figure out and samples to be done, but one of my biggest questions is what type of fleece I should buy that will allow me to spin a strong enough warp. I anticipate having a fairly long warp, and I know that handspun yarns can prove to be temperamental warps. I'm thinking that medium/crossbreed wools would be the best for me to use as a begginning handspinner, perhaps a Coopworth, Corriedale, or Romney? Once I decide on a sheep type I can buy some rovings to play around with before starting the project, and I can figure out whether I need to double-ply, or size it or spin it tightly.
Thanks for any help!
