Week #20 - Double Decades
I love that these two "X" blocks represent the number 20 in Roman numerals. An assortment of half square triangles (HST) and Connecting Corners (CC) create the gold X in each block. After a year of practicing these techniques, it's all easy peasy. Make sure all of the elements of each block - the center 4-patches, the star point units and the corner HST 4-patches - all measure 4 1/2" square before assembling the block. This will ensure the completed block finishes the correct size (12 1/2").
Once you've pieced the Double Decades blocks, you're ready to assemble the final Section #4. Lay out the remaining blocks, as shown. Piece in rows, as directed. There is a place next to the corner log cabin block that requires a set-in seam. Leave a couple inches unsewn when sewing the top HST row to the Double Decades, as shown by the dotted lines. Pin and sew the log cabin block to the side of the Prairie Pinwheels/HST, then pin/sew to the String of 9-Patches, completing the open seam. Take it one step at a time and it works out perfectly.
Speaking of applique, I would add the fusible, topstitched appliques before sewing the four sections together. It's easier to handle the smaller chunks of quilt to add each applique. When I pieced my quilt, I was still figuring out the appliques, so I didn't add them until the top was completed. The second time around, I added them as I completed each section.
See you in a couple weeks to talk about the pieced borders. Happy Halloween!
