Here’s an idea for your NEXT year’s fair entry! The stitch pattern is super interesting ... it’s done in “rainbow” and then there is one in blue/white . It looks like good instructions/photos on the pattern. Both blankets are gorgeous in different ways due to the colors used.

Oh, VERY pretty! And you’re right - it looks great in a variety of colors.
It looks like you could easily see if you made a mistake before you got too far along. (Always a good thing for me, LOL!)
