My husband's cousin, Crystal, and her husband, Justin, recently asked for my help in redecorating their basement after it was destroyed by flooding last September. I gladly accepted and we've been working on making it a fun, inviting space for their family to hang out. One of the projects I'm helping Crystal with is making new pillows for their existing couch. Since they have 2 kiddos, I knew it would be important to make them washable. This is why I chose to do zippered pillows.
I was flipping through my sewing machine guide book a few months ago trying to figure out how to use my zipper foot and I came across a tutorial on "how to install a zipper". It is by no means a new method, but it has helped me tremendously, and I'm hoping it will help you too.
