Two out of three snowmen done

Well, I finished "Willy" the second of my three snowmen....still have "Milly" to do. The pattern is a "Stitchy Kitty" pattern called "Snowman Trio". The fabric is a little blue-er than the picture shows. The pattern also calls for buttons to get attached in the snowmen's arms. Chilly has a couple of snowflakes to hold on to, Willy is holding a cardinal and a bluebird, and Milly is holding a couple of hearts.

I think I'm going to create my own tri-fold out of these when they're done. My thinking is to mount each one individually on a piece of matboard or foam core (with some quilt batting) and then do three more pieces of matboard covered with quilt batting and fabric (I'm thinking of - if I can find it - white fabric with light blue snowflakes...if not, I'll find something with snowflakes or snowmen on it).

Then my thinking is to take one stitched piece and one fabric covered piece, and put them together with ribbons between them (like 1/3 of the way down from the top and a 1/3 of the way up from the bottom). If I do that with two of them (with the ribbons coming out of opposite sides on each) and then sandwich the ends of those ribbons between the third set, I think it will work as a tri-fold. (Notice - I said I THINK!) If anyone else has any brilliant ideas to contribute....please feel free to chime in!

Thanks for looking!
