You do not sew alone like this!! I've been sewing since 2012. When I first started sewing, I was doing dish clothes. I thought that would be the only thing I'd ever sew when I bought my first machine. 4 machines, 1 long arm later, I am still not matching up my seams until most recently. That particular quilt top still was off some a tad bit and still had to square it off on one end. The fabric was cut and sewn as per directions. Bottom line is that the recipient will see the beautiful creation you made. So what if your FMQ isn't intricate, mine is far from it, but the recipient won't know any different. I sew/quilt because it soothes my soul. When it's gifted and they are blown away that it's so beautiful (in their eyes), then I've done good. Don't get discouraged, I believe many will tell you that we all start from the ground up and we have all had our share of bloopers! Glad you posted this because I took a quilt to work to pin during my lunch hour. I got it all pinned and nearly to the last row, I flipped it over to be sure there wasn't any puckering in the back. Come to find out, the backing was upside down!
Maybe you could find a sewing buddy or even do a virtual sewing buddy time to work on a project. That's what I have done the last few weeks. I love it because I have that me time and get to spend time with my friend who lives in another city. Happy Quilting!!
