Welcome from South Louisiana. I've been quilting since "95 and still consider myself a "beginner" because I still work with the simpler patterns. I don't have enough years to ever be able to make all the patterns I would like to make. I love cutting and piecing, and yes, I still pin. Thanks to this board I have taken UFOs out of the closet and boxes and have completed a few of them. All you will get here is kindness, friendship, love, encouragement, and support. They have answered my questions and listened to my woes. When I don't know something, I ask. And I don't know a lot of things, but sometimes I find that I DO know enough to share with one that is more of a beginner than me. :lol:
As far as that complex first pattern of yours, I agree with many. You can do what some have suggested and put it all away in a safe place to get back to when you are more confident and skilled. OR you can chalk it up to experience and use the remaining fabric for another easier project. Keep the block/s that are done to use in another way. Perhaps one day you will make a sampler and you can use it as the starring block.
Good luck to you. Keep us posted on your progress.
