To figure out just how much fabric it takes to make a pillow you need to know how big your pillow form is. If you are buying new the packaging will tell you. If you are recovering a pillow, check the tag on the pillow for a size. Otherwise measure the pillow with a cloth measuring tape as best you can. Whatever the dimensions are cut your fabric the width by 2 times the height. For example if you are using an 18"x18" pillow form. You would need a piece of fabric that is 18" wide x 36" tall, or two pieces of fabric that are 18" square. Use a 1/2" seam allowance to sew the pillow. Making the case slightly smaller than the pillow form makes a very full, filled out finished pillow.
So how much fabric do you need to buy to make two pillows? If they are 18" tall or smaller than one yard of fabric would make two pillows. If they are bigger than that we would be happy to cut a special size perfect for your project. Send us a message and we can figure out the details with you.
One quick exception to the rule is if you plan to make an envelope style pillow. (There's a good tutorial here if you need one... http://freshly-picked.com/pillow-tutorial-envelope-back/) Since the back overlaps you will need slightly more fabric. The link has some explanation for figuring out fabric amounts as well, but please let us know if you run into trouble. We are more than happy to help.
If you haven't invested in an invisible zipper foot that fits your machine, it's definitely something to look into. Sometimes also called a concealed zipper foot, this thing is amazing! We dare say it's the fastest way to make a pillow and you end up with the very best results. I do understand however that not all invisible zipper foots are created equal, so it's definitely something you should research for your machine before you buy one.
