I never buy throw pillows (okay, hardly ever). I feel like I can make them quickly and inexpensively. I'm not a major sewer, but if you can sew straight lines, you can sew this!
The first thing that you want to do is measure your pillow.
My pillow was 19" square. Then, I cut the fabric for the front of my pillow. You will want to cut your fabric 1" bigger to allow for 1/2" seam allowances.
The back of your pillow is going to have 2 pieces of fabric that overlap. This way, you can take the fabric off and wash it easily. To cut the back pieces, you will want them to be half the size of the pillow plus 2-3". So, I cut my pieces 13". Then, you will need to turn over one edge of each of the pieces. These are the edges that are going to show when you have your finished pillow.
The next step is to pin your pieces of your pillow together. You will want to lay the front of the pillow on a table, front side up. Then you will want to lay your two back pieces on top of that front sides down. You will want to have your turned over edges on the inside of the pillow, overlapping.
Pin all around the outside, then take it to your sewing machine and sew all around the outside edge. Flip your pillow right side out and stuff your old pillow inside!!!
This project takes less than 1 hr. (it probably took me longer to post this on the blog.) It also is quite in expensive if you already have a pillow that you are just recovering. All it costs is the fabric. For this one, I used just a little over 1/2 a yard.
Good luck and email me if you have any questions.
