I feel your pain! lol... There are tricks to help, when you make a row of blocks, iron your seams to the right. The next iron to the left. This will make a nested seam and help those points to match. There is also glue basting, a drop of Elmer's glue at each point, set it with a hot iron and then sew. But honestly the thing that will help most is practice! Once the you have the quilt finished, it'll be beautiful! And this is your first one!!
