You're a beginner quilter and your block looks that good? Congratulations! You're off to a very good start. I first noticed your lovely fabrics and the block choice. I'm with the others who are impressed with how well this turned out, given your lack of experience.
Nothing to add here, just chiming in on what works for me:
1. Take two scrap strips (maybe 6" long) and sew about 2 inches. Then measure with a ruler to see if you have exacty 1/4". If not , adjust a little for another 2" . Measure. Don't veer off at the bottom--stay straight. Most times the veering happens when we get too excited about being "almost at the end!"
2. I use a 1/4" quilting foot on my machine. It saves a lot of time (no measuring involved).
3. I use Elmer's glue to get points matched. It's a personal preference--pinning accurately works well, too, but with glue, there's nothing to remove, nothing to accidentally run over, nothing to poke you.
4. Don't rip out your first block's mistakes unless you are very short on fabric. The points are not drastically off, and if you use this block to practice quilting as well as piecing, it'd make a lovely pillow cover. Or just keep going with the next block and don't worry about this first. Think of it as your kindergarten block, and move on to first grade!
5. Be careful before taking apart something more than twice. The fabric near the seam will start to fray. I found that if I rip something more than twice, it gets frustratingly wonky. Decide what you can live with.
Best wishes as you progress!
