My sewing background in mostly in costuming and dress making, yet my fabrics don't seem all that dress maker-y since I get caught up in the 2-D design. Playing around with this stuff is a blast though!
I love how you have used bold colours and simple floral shapes to achieve the naive patchwork / folk art style of your cheater block! After reading your description, I had another closer look at the individual elements you have used in your design. They hold echoes of the bright and funky fabrics that I loved when I was a teenager during the "Flower Power" era!
