Good luck.

very nice idea.
I got the gingerbread house from Urban Threads n sale for $1.50
it's 3d stand up about 4" x 3 1/2" x 4". it's done on ultra Solvy.
Getting a jump on next year too.
Please show us when it's done.

Would the fact that they are different size blocks trip you up. for instance you would have different size panes in your window? Just asking.

Great project to look forward to. You will have a whole year to finish it. Good luck...

I think it would look beautiful and look forward to seeing it. I have seen where people cut up panels and put them in attic windows.

You would be sewing the embroidery in blocks....so you would not cut the embroidered blocks....just join them attic window style. I agree the sashing may distort the design and not be happy can you enlarge the picture on this site and cut it apart before you purchase the design?

To avoid distortion, you could stitch the blocks together then applique the sashing over the "panel" avoiding going over faces, and important portions. I did this on a panel, but it was much smaller than this would be. I used narrow sashing strips. It worked out pretty well.

I have embroidered many of Anita Goodesign's wall hangings. They are heavy but beautiful. If it were me I'd embroider the "C" size, it would be 34" wide x 24" tall. Then as a few borders to it and bind it. It would be a lap quilt instead of a bed quilt. The scene is kind of busy and I think an attic quilt would be too much and the scene would be distorted.

I think turning it into an attic window would probably not work but hope to see the posted results of how it worked for you. I just got the "Night Before Christmas" design by OESD and am stating 2016 gifts too.

There's a lot of food for thought posted so far and I agree it may be difficult to determine what to do so you project isn't distorted HOWEVER, that being said, it should be a WOWZER! Good luck
