Then below is my step by step. Let me explain what I did; I made a small prototype so to speak using tape so that I could pull it apart and rearrange to experiment with the color variations. I bought 3 shades of green and 3 shades of blue both with a dark, medium and light shade. I got enough to do blocks in using both, but since you are only producing one block, you can choose all blue shades, all green shades or a combo of both as my "finished" blocks will show. I will demonstrate the cutting patterns and give measurements, and then show the finished products. Keep in mind these are miniature blocks shown on here. I wanted to go ahead and post so you can begin if you wish. I will show my completed block(s) in the next day or two. Have fun with the combos you choose and the visual effects that are produced by where you place the darks and lights.
The picture below... I was trying to show you use two large blocks in dark measuring 7 & 1/8 inch square and then two smaller blocks in two different colors-one a medium and one a light color (my light is a yellow green) these measure 6 & 7/8 inch square. For a total of three colors but four blocks.
Next, on the 2 large dark squares (one color) cut diagonally from corner to corner, you will have four large dark triangles when it is completed. Cut double cross cut on the 2 smaller (two different colors) squares so you will have four small triangles of a light color and four small triangles of a medium color, though I only show the light color of the smaller ones in the shot below.
In the online tutorial it shows how you put them together: stitch one light color and one medium color small triangle together after placing them together in a way that 90 degree angles form the midline of the new triangle the form see the picture on the website. Do this x 4. Then sew that portion to the large dark color triangle on the long sides so that when it is completed the large dark triangle when facing you is on the bottom right and the block it forms and the multi-colored double triangle is on the upper left of the block with the medium portion showing as the inner triangle (see web site).
The examples I show below are two completed small prototypes that I taped together so I could pull them apart and switch the colors. The following pictures are of the all blue on left and all green on right. Keep in mind I did not use exactness and they are smaller than the actual blocks will be.
The last shots are showing how I switched out the light green to the blue square and the light blue to the green square, for my own curiosity and to help you in making your decisions as well.
There are numerous possibilities which is one of the fun things about quilting.
I wanted to get these on quick but wanted time to play with color variations before I posted my finished block(s). I will post the real ones in the next few days.
I hope this is an adequate explanation and guide and that you have fun doing this pattern. As I researched, if you are not familiar with quilting as I am not, I was simply amazed at the huge number of variations on the pinwheel pattern. I picked a very basic simple one but still catchy to the eye. If you have any questions my email is beki@bekigraham.com. which you may since I am doing this at such a late hour and my brain I think has already gone to bed. Thank you! and Thanks to my dear husband who took the pics and got them into this blog site for me!
