Sewbizgirl, I LOVE your quilt! I want to make one like this for my bed!
I'm planning to make a baby quilt with a few charm pack and use the coordinating mini charm to put prairie point on the border. Having all those 2.5 square already cut should speed up the process.

2.5" squares are the perfect size for 1" hexies. Hexies are measured on the side, not across. (I now add that because for years I did not know).

where did you find the sale for your mini charms

I bought a mini tumbler template from Missouri Star Quilt Co and a candy pack but haven't done anything with it yet.

Sewbizgirl--love the quilt---and the mug mats are a great way to use those tiny squares.

Missouri Star has a video tutorial for a Christmas table runner using them. I did one , from start to ready to hand stitch the binding on in less than an afternoon.
