I'm not Good at Sewing

Yesterday, I sewed a curtain for the small window at the entrance. Even though I call it a curtain, it doesn't have any pleats; I just hemmed all four sides of a single piece of fabric. I'm not good at sewing. I rarely use a sewing machine. At first, I had a bit of trouble because the sewing machine wouldn't work properly. Somehow, after about an hour, I managed to sew all four sides.  However, I then realized that I had folded back the last side in the wrong direction. I had to undo the stitches and sew it again. In the end, it took about an hour and a half to finish sewing.
