Careful there girl, or you'll have to go to OAA meeting - Over-Achievers Anonymous, lol. Take it from your twin-separated-at-birth, start with a pattern that has squares and /or rectangles. Maybe a few triangles. Just trust me on this, you will thank me later. And baby quilt size is another very excellent idea. (My fist quilt was a t-shirt quilt, full size or bigger, that I made for a gift. Lol, no pressure, right?)
One thing no one else has mentioned yet is *how* to get that all important 1/4" seam allowance. It seems like it won't make any difference of its the same for the whole quilt, right? That was what I thought, but wrong! So, here's my contribution to your online quilting education, lol. It's the quilting equivalent of learning to knit in the right guage.

After I did this, I wished I'd known about it before. Good luck!
