This is the block I chose for my Pinwheel Block Swap on Flickr. There have been a lot positive comments and requests for the block, so I am posting the pattern here for everyone to enjoy. You will need to print 2 copies of each page to create the pinwheel. The templates are numbered in the order to piece them. They are also lettered but you can ignore the letters
You only need a basic knowledge of paper piecing to complete this block, which is why it is such a good one to start with. You get stunning visual results with any color combination! You can piece it anyway you like, or you can follow the tutorial below.
Cut out your templates and place them into two piles as shown. 4 blocks will have corners, 4 will not. Pick out the fabrics you want for each part of the pinwheel.
I like to pre-cut my fabric strips. This way I know I have enough to cover the block, and I can chain piece my block. The templates with corners are numbered 1-6, the templates without corners are numbered 1-5. For the sake of the tutorial I will refer to the numbering for the blocks without corners. The templates are identical once the corner is sewn.
The numbers in the brackets indicate the position numbering for the templates without corners.
Cut your fabrics as below:
1 = 2 squares 4 ¼”x 4 ¼”” cut into Half Square Triangles ( yields 4 HST)
2 (1) = 8 strips 6″x 2″
3 (2) = 8 strips 3 ¼” x 2″
4 (3) = 8 strips 5 ¼” x 1 ½”
5 (4) = 8 strips 5″ x 2″
6 (5) = 8 strips 4 ½” x 3″
Start with the 4 templates with corners. Place the HST right side up on the unprinted side. Take strip #1 and place it Right Sides Together on the HST, as shown below. Hold the block up to the light, printed side facing you, so you can line up the seam allowance. Sew on the first line. Repeat for the remaining 3 templates.
Press the blocks ( no steam). Place a straight edge along the next sewing line, fold the paper back along that line (tearing paper from the previous stitched line as needed), and trim the seam allowance to ¼” using an Add-a-Quarter Ruler (or whatever your preferred method is). Set these pieces aside for now.
Take your 4 Templates without Corners and place strip #1 Right Side Up on the unprinted side of the template. Use the light trick to make sure the entire section is covered. Baste the strip in place on the dotted cutting line or in the extra paper outside the template. This will hold your fabric in place. Place your straight edge along the sewing line, turn the paper back, and trim the seam allowance. (It is the same line as shown above)
From here on you can piece all 8 templates at the same time. It goes together quickly from here!
Take strip #2, place it RST with strip #1. Sew and press. Place your straight edge along the next sewing line and trim the seam allowance as before. Repeat these steps for the remaining fabric strips.
Here is a photo montage of the rest of the piecing process (‘Cuz everything is better with a montage! MONTAGE!) Enjoy!
Trim round the templates on the dotted line. Voila! 8 wedges ready to be sewn into your block!
Place a no-corner wedge RST on top of a with-corner wedge. Pin together at the top and bottom by placing a pin through the points at the top (black) and bottom (white) so it is loose, as shown. Line up the seam allowances. Hold the bottom firmly so the pieces don’t move and secure by pinning normally.
At the top there is a lot of bulk because you have seams meeting as well as the paper. If you were to pin through all the layers you end up with a humped area that can be bulky and messy to sew through.
To avoid this you need to pin through the FABRIC ONLY. This keeps the pieces from humping up.
Through the fabric only
Sew the seam, pull the paper out of the seam allowance, and press your blocks in the same direction (this is important later!). You now have 4 quarters. Sew your quarter together into half blocks using the same process outlines above, making sure that the bottom points are well matched. Sew your seam and press in the same direction as before. Your points should match.
Sew your final seam, pinning at the corners and at the center point. If you want to make sure your points match, use the technique from the Wonky Compass Tutorial, or you can pin and sew just through the center, then open and check your alignment. If you are happy with the alignment sew your final seam. Press the last two seams in the same direction as the rest, and use the technique from the Wonky Compass Tutorial to press your center flat. Tear out your paper and do a final press with steam. Trim and clean up the edges of your block, and your done!
