I make applique flags and banners and use large panel scenes for my door and have a post that I put the flags on and have the holder for the flag that you can get at a hardware store. I use simple Christmas designs from coloring books and in large them for applique. I also make wall hangings for the holidays that I make and hang on my walls with dowl sticks and the fabric is just one layer of fabric,
but it is not a wall quilt. Menards has lots of different banners and flags if you just want to buy them or go get ideas.
