Yup ... clear as mud and somewhat what I was thinking.
Sooooooo ... the gist of it is, you do 4 Prairie Points, which perfectly match together when sewn in place. From a distance it looks like a QST (if you use different fabrics) ... and then you can lift them to see whatever is inside.
Looks to me like it'd be a FUN addition to any kids blanket .... something to fiddle with and something to investigate.
And too, wouldn't they be perfect here and there on an I Spy?
Great idea .... and I CAN figure it out from there ..... now that I have a mind's eye to it!

THANKS Tartan!
