Two days later I have made 25 blocks the same way.
One pair of jeans gives new life for 7-10 blocks depending on how big they are, how worn are etc.
I used different colors which gives additional effect in design.
I decided to make running stitch on the denim stripes.
I have stuck a paper tape on the ruler to know where to mark a line without measuring every time.
Still wandering if add FMQ on color pieces...
