I smile at your enthusiasm because I was the same way 15 years ago. I also thought I could do ANYTHING if I was willing to put in the time and effort. Not so. Making a quilt is exacting and there is a learning curve that everyone has to experience. First of all, don't make a quilt you know is difficult. You could be so exasperated that you quit in the middle. I don't know where you're getting your fabric or your quilt patterns, but you'll need to get the approprate "tools" (rotary cutter, mat, rulers, etc) If you have access to a quilt shop it would help a lot. Why not put a stack of fabrics (any size is okay, but I'd suggest 4"). Figure out how you're going to get a consistent l/4" seam (that's VERY important) and sew your blocks together working so the seams go together in all directions. Takes a little practice, believe it or not. There are many, many techniques you can use but you will need to learn them as you advance in your quilting projects. I say 4" squares (all cotton), then put a border around them. You'll learn as you go along and I hope you enjoy the quilting process as much as I do.
