If you are really too nervous to do that one, (I'd say just jump in and go and you will do fine), but you say you are scared. So...I would advise you to either whip together a quick little quilt- even just baste something together, then sandwich it and quilt away. That way...its only a true "practice" quilt and you won't be worried about messing anything up. After you've done this, you will know that you can do it, then start the cowboy quilt and have fun.
