I'm almost too embarrassed to post these on here because they were so simple (and free!). Everyone has those wooden letters from craft stores and you could spend a small fortune buying up the alphabet. It dawned on me one day that I can make my own. I have yarn out the wahzoo (Did I spell that right? Is it even a word?) I cut letters out of amazon boxes at 12" tall and covered one side with glue. Then I wrapped yarn back and forth until the entire letter was covered. To keep the yarn in place while drying, I attached a paper clip. And that's it! Next time I'll aim for cutting straighter lines. ;) I consider these to be very abstract or freeform.
