Cutting out the fabrics to make Optical Illusion is pretty straightforward. Just follow the cutting instructions on page 2 of the Optical Illusion Quilt Pattern. You can reference my previous post on choosing fabric color combos that will work. For my version I used highly contrasting black and white for the squares with gray for the long skinny strips.

Before cutting, I highly recommend starching your fabric. This will keep the smaller skinny strips from stretching out of shape and will give body to your pieces as you handle them. I like to use inexpensive starch from the grocery store. I spray one side of my fabric and iron from the opposite side. Then repeat for the other side. It works like a charm!
Cutting the Squares
When cutting the squares, the easiest way is to first cut strips from your fabric, then subcut those strips into the square sizes as indicated in the pattern. If you are using a directional fabric like I did, you can choose to have the print always running in the same direction, or let it be more random. The choice is completely up to you depending on the look you want.Still need the Optical Illusion pattern? Get a printed version or get the instantly downloadable pdf. Refer to the quilt pattern for the number of squares to cut for your size.
When it comes to cutting the rest of the units that are a slightly different size (for the starting and ending rows), be sure to label them to keep the sizes organized. I’m constantly referring to my pattern for unit size and placement so I keep everything in the right spot!
Cutting the Skinny Strips
When you are cutting out long skinny strips, you’ll either need to piece together shorter lengths of fabric to get a long enough piece or you can rotate your fabric and cut them parallel to the selvage so that there aren’t any seams. This is the method I recommend in the quilt pattern.
Cut long strips parallel to the selvage.
You can fold your fabric into about four layers by shaking it out so it hangs straight, then folding it in half, and half again parallel to the selvage. If your folded length of fabric is longer than the width of your cutting mat, I recommend getting another cutting mat and another ruler so that you can line things up along the entire edge.
Once everything is cut, you are ready to start sewing your pieces together next week! Feel free to take your time, or work ahead. The choice is up to you and you are the boss of your quilt!
