Thanks for all the feedback! I did my second tea towel and played around with satin stitch some more. I think I do neatest by outlining first, then filling in with the satin stitch. I am not neat enough yet to satin stitch without outlining but I will work on it. Here's how the tea towels came out, I made them as a gift for some friends who let me stay at their house while I was travelling for work:
I am having so much fun with this I'm branching out. I finally thought of something I could embroider which would be cool enough to give my brother! A guitar strap! I bought a cheap black strap ($6) and some nice black fabric and I'm going to embroider on the fabric and then sew it to the strap when I'm done (hide the back!) The black wild cat is the first bit on the strap. I am going for sort of a dark forest theme with nocturnal creatures, dark pools of water reflecting the moon, big dark spruce trees with silver moss, etc. Not sure what else I will add. Now I wish I had waited to start until I could get Jenny's rock and roll! I LOVE the big old amp.
