Step 3: Sewing
2) Then you can unfold it, and the two blocks will be joined together with a ridge between them.
3) Continue to sew the blocks together this way until you have a horizontal row.
4) Then sew the rest of the horizontal rows.
5) Once that is done, you can sew the horizontal rows together basically the same way; just sew each block to the one next to it to make a ridge just like you did with the last blocks. When you sew the horizontal rows together you will have to start and stop between the ridges, because most sewing machines can’t sew through that much fabric.
