It's looking fantastic!! I remember when you first started and I thought "ow ... not a great choice for a first quilt" but then you posted your first few blocks and they looked so good I knew the whole thing would come together for you ... and it is!!!
Curious ... are you removing the paper before you do the Y seams or are you doing the Y seams with paper still intact?? I ask because the first time I did Y seams with paper pieced blocks I removed the paper first (thinking I couldn't possibly do a Y seam with the paper still intact) and I had the usual Y seam distress (some good ... some needed a ripper). The other night I was making a block that was PP and I had changed the pattern a little and had not thought ahead far enough .. found myself in a sticky situation where I had do Y seams with paper pieces. So I jumped right in and sewed my Y leg with the paper in place. It was sew easy!!!
