What did I learn. Forget the fancy thread. I used a variegated brown/rust/tan thread and it doesn't show. The stitches sink down into the fleece and make amazing texture.
Another thing...tension problems don't show! LOL! And...going off the *lines* a bit doesn't show either! The Innova handled it all like a champ, no thread breakage, hummed along..took about 5 hours to do the first one and I am pleased with the results.
Practicing on muslin in one thing but actually having something to show for the practice seems to suit me better. And the fleece is so forgiving that the finished product is actually something I would give to someone.
And, yes, I ordered more fleece.... ;)
