Rebecca's rows - this is going to be a stunner!

Warning Rebecca about her red

Rebecca, when I started piecing your blocks there was a bit of extra starch on my iron that smeared on the red of the first subunit.  I took it to the sink to rinse then laid it on table to dry.  I flipped it over to iron it this afternoon and noticed that the seam allowance and white thread were now pink.  the body of the block appears fine but I wanted you to know even though you prewashed your red, it is still bleading some.
