Recently my mom and I have been playing with the disappearing 4 patch quilt technique. This post card is a result of that process. She felt that the one part was cut too narrow and it didn't make for a nice quilt block. Once she trimmed it up and fused it to some interfacing, it makes a wonderful postcard. Lucky for me, I was the recipient. The technique she tried is illustrated in this post from my quilting blog.
The colours are a bit off, it should be more yellow and purple. Measures 4 x 6 inches.
This is the quilt top that I made using the same technique. Details are shown in the post linked to above.
