However, you have to also consider how the fabric will look when it's cut and pieced into your blocks, how much of each will be used and where it will be placed in the block. I'm only now really paying attention to the size of these blocks --- they are supposed to finish at only 7". When you consider how many pieces are in some of these blocks, that makes for some pretty small cuts! Compare how the fabrics look in Block #3 (above, center) and how two of the same fabrics look made up in a 6-1/2" (unfinished) Bow Tie block which is made with fewer and bigger pieces. Going forward, I'd do well to cut preview shapes to use when auditioning the fabrics I'm considering. I may re-make Block #3 at some point in the future after I see how it looks among some of the future blocks.
However, after making them and then laying them out to prepare to piece them into the block, it became evident that the HSTs weren't the right size. Huh? I went back online to AQS and called up the instructions for that block and sure enough, the instructions had been changed to making them 1-1/2" unfinished! Now that worked in the block design and fortunately, I could just trim what I had already made down to the right size. Anyway, I still got to try out the die too so it's all good!
The small squares and rectangles for Block # 7 could be easily subcut with the Stripology ruler.
