I think you did very well and should be proud of yourself. I'm still working on my first quilt which I started 3 years ago. I still have to put the binding on. My first quilt cost a bunch because of all my mistakes in picking out fabric. The local quilt shop lady really helped me "fix" the color scheme. The quilter who quilted it for me had to take off the borders and square up the inner part before she could put it on her machine. That cost a bunch more. It has turned out well and I'll put in on our bed soon.
So don't be discouraged, just start on another project.
I'd post a picture but I don't know how (maybe my granddaughter can teach me.)
