As the others here have suggested, it's often a good idea to put your project away and do something else. But how about something that is completely different, but still sewing related, like a new approach to the whole sewing process? For example, when you say you don't like working with patterns, does that also include patterns you've made yourself, from scratch? Since you've taken sewing classes this might be old news to you. If it is, try out a different technique or a new kind of garment, but at least for me the triggering factor of my (relative) success with my darling sewing machine was experimenting with a skirt sloper. Making your own patterns really gives the process of putting together pieces of fabric a new, more logical, perspective. And it's much easier than it might sound.
I am not familiar with skirt slopers. That sounds really cool, and I will look into it.
What is it about using patterns that you don't like? Is it to do with the physical processes of laying out and cutting (my personal bugbears!) or is it the restrictiveness of following instructions, or a shortage of nice designs, or what?
Well in the fashion class we made pattern based pajama pants. She helped us alter the pattern in length and size to assure a good fit. However upon completion, the fit was ALL wrong. In other words, the pants were HUGE! The same thing happened a few years back when I made pj pants at a friends house. I don't know if they were just bad patterns, but I've been turned off from patterns since then. Plus the thin, easily torn paper frightens me. And I feel restricted and all-together uncreative.
