Yes I how have a hole in my middle finger from pushing the needle through these hexes! They are laced onto the plastic base hex and then ladder stitched together, then couched with gold trim. I think it is going to turn out bigger than I thought it was...the books measurements are in metric and I am not so good at judging the size of things based on cm.
Here are the pics so far! I will be so happy when all the couching is finished, but it does add alot to the design!
