The Attic Window quilt pattern is a traditional quilt pattern that creates a three-dimensional window-like quilt design. A square made from half square triangles and two rectangles are arranged around a larger square which represents the window.
The Attic Window quilt pattern is a great pattern to show off large designs, or even cut up a panel for the squares so that it looks like the viewer is looking through a window!
There are different ways to make this block. The traditional Attic Window quilt block required cutting on the bias and sewing a Y-seam or mitered seam for the corner of each block – none of these is easy!

How wide is the sashing on an attic window quilt?
The sashing can be any width you like! In my example above, I did not including sashing between the blocks. Sashing is small strips of fabric between blocks to give them separation. In an attic window quilt block the sashing between the blocks represents the window panes. If you want to add sashing, I’d make it at least 1/4 the size of your sides of your blocks or the smallest of 1/2-inch wide – any smaller will be difficult to manage.
How do you make an easy attic window quilt with a panel?
First you need to select a fabric panel that has multiple smaller designs that would be suitable for this technique. For example, find a panel that has a selection of designs that are 5-inch or 6-inch block. Next, you would cut those out and then add the window frames to one side and the bottom of the panel blocks.
