David, why do you need to feel guilt?
I am a "process" person. That is, I prefer to explore the process of making something, but don't really care if it ever gets finished. I have learned or at least, tried just about all the techniques. A "project" person is more about making and completing a project - quilt for the bed, table runner for dining room, etc.
I believe that by trying out all the techniques is how we develop into the style that defines us. Some of us never find that style, but sure have a boatload of fun exploring! Not to mention building our stashes!
This is not to say that I don't ever finish anything. I have a gallery of quilts on the walls of our hallways & in most rooms (even the guest bathroom!) There are quilts draped over the furniture in the living room. I have beaucoup sets of placemats.
Right now, I have turned into a project person as I am madly working on finishing a Dear Jane style quilt with another group here on the Board. I started her in 1997, and joined this Board when I discovered this group. I am even going to host a Cyber-Sew-A-Long in a couple of months. This Board would probably throw me off if I were to list all that I have in the works. Would take too many megabytes. :)
Do I feel guilty? Not one little bit! And you shouldn't, either. You are exploring and along the way, will be quite a few discoveries. Some might get finished & others, well, maybe not. But there is nothing wrong with anything "quilty" that we do (or don't do.)
Good luck with your passion!
Kathy
