Thin and thin yarn

So, as you can tell from some of my work , I absolutely love to crochet with super bulky, handspun wool. Merino is my fave, I found a great lil shop on etsy that i am completely obsessed with. The colors and saturation of their beautiful yarn is like no other. Unfortunately, they are almost always sold out. You almost have to check everyday to see if they have new stuff before it's sold out. I keep thinking how i might save a buttload of cash if i learn how to spin myself....any ideas????? I'm not really sure where or how to start. It might be more work than it's worth, and i will just continue to support this lil outta the way store with beautiful product:)While your checking them out, check me out on etsy, i will post both links below, let me know what everyone thinks:) i love feedback.
