Wool Couture Company is a UK-based Etsy shop established in 2014 that specializes in knitting, crochet, weaving, and macrame craft kits.
You can get one of three kinds of kits: a Basic Kit, which comes with a loom and instructions; a Starter Kit, which comes with a loom, two weaving needles, instructions, a mounting bar for hanging, and a cotton ball of warp to hold your work; and a Quintessential Kit, which comes with everything in the Starter Kit, plus the merino wool for weaving.
Promising review: “It’s simple to use, the wool I received in the set is of a high quality and the service was smooth and communicative. Can not recommend this highly enough from a first-time weaver.” —DivineDerbyshire
