This makes a pattern that is 21" from top to bottom. If your fabric is not that wide from the top of the selvage to the fold make adjustments in where the line is drawn. For example: for a 20" width the line would be drawn 2" away from the edge of the freezer paper.
Pin your pattern to the fabric with the small edge at the fold. Place ruler along the drawn line and cut along the angled edges.
To keep this post from being so long the tutorial for the pieced border is in the next post. You Can See It HERE.
After the pieced border unit is made attach it to the wedge matching centers. Place the 60 degree line along one of the straight seams and trim the angle through the borders.
You could stop and finish it at this point if you like the size. I added one more 4 1/2" border of the center fabric. Then all that was left was to sew the wedges together matching seams at the borders. Leave one side open for a Tree Skirt or stitch them all shut for a tablecloth.
Tip: You may find quilting easier if you stitch all the wedges together, quilt it then split one seam open. It is easier to baste and handle that way.
Quilt as desired and bind. Make ties or use Velcro squares for closures along the open edge.
Simple stippling around the squares make them pop. I did a larger meandering on the center print since it was so busy nothing fancier would show up anyway.
Final size is about 70" across and 80" point to point. I know that sounds huge but I have seen many live and artificial trees that it would barely be showing out from under the branches. A tall tree stand takes a lot of it up vertically.
To use this as a Tablecloth seam up the last two wedges and applique a circle or hexagon in the center.
