I finished it all! Totally! Here is my border/background quilt with my seasonal wool wall hanging on it! The cool part? How I have the seasonal wool part attached.
I"ll zoom in a bit. Yup, I used rare earth magnets. Boy are those things strong!
On the back of the wool part I made little pockets and sewed a magnet in them. Then when I want to hang it up on the background you just hold another magnet up on the back of the border quilt and it sucks right up to the one on the wool mat! Is that cool or what! So now I can make different wool centers for each month of the year, and just change them quickly with the magnets!
And look - it works on the fridge too!
Here is the border/background quilt without the wool center. How fun is that!
