I normally mark my cutting and sewing lines with a mechanical pencil and regular lead but this time it didn't show up on the dark purple. I looked through my pencil holder and a found a mechanical pencil that had yellow lead. It had belonged to my husband's sister and after she passed it was included in the stuff I received from her - thanks Wanda!
I am happy with the way my block finished up but if I was to choose my fabric again I would definitely choose a directional fabric instead. The unique piecing design of this block is lost in my block because of the all-over pattern of the fabric. You can still see the way the block is pieced if you take a close-up look though.
