I made the quilt as a BOM. The first 3 blocks are the same size on the side seam. I sewed each of these blocks together as I finished them. As I made additional blocks, I placed them in the proper position on my design wall. When I completed block 7, I could sew the top of it to the bottom of block4. The bottom of block 5 was sewn to the top of block 8. I then sewed the Block 4 segment to the block 5 segment. After I finished block 9, it was sewn to block 6 and the segment joined to the blocks 4 and 5 segments. This completed the bottom part of the quilt which could then be sewn to the top (blocks 1-3). The blocks you sew together match so joining them is easy. You just can't join them in the order they are completed. I really like the borders. I almost left out the snowman head on the top border. Fortunately, I noticed it in time to include it. Best wishes on your quilt! I so enjoyed making mine. Of course, I haven't quilted it yet.
