Pat suggested that I do a tutorial on how to attach the zippers to the little bags I am making, and I thought it was a brilliant idea. I am not going to show you the details of the whole pattern, because I want you to buy it (Zippy Strippy by Atkinson Designs). However, the zipper instructions are pretty generic, so here we go.
I bought my zippers at Prairie Queens, my local quilt shop. They are really inexpensive, because there is no packaging. As you can see, they come in every color you can think of. Just one size though. How does that work, you ask skeptically? Just watch.
Then, you will sew a little tab on this end, just like you did on the top end.
This is what you have done with that zipper. Throw the cut off bits away.
Place the zipper right side down on the outside of one of the bag sections. Be sure to leave an equal one half inch on each end of the zipper. This is important, and you will be sorry if you don't measure at this point. Unzip the zipper half way.
Put your zipper foot on your machine. Make sure you adjust the needle position to the left. (Or your needle will come down right on the middle of the zipper foot and you will break your needle, make a terrible clunking noise, and scare yourself to death. Do not ask me how I know this).
You can sew the zipper on with the zipper zipped or unzipped, but when you get to the zipper tab, stop your machine with the needle in the down position and zip or unzip the zipper to get the bulkier tab part out of the way.
So, your zipper is in, but you aren't quite done. You are going to do a little top stitching. Lengthen your stitch length a little. It makes the stitching come out neater looking. Open up the bag and stitch about a quarter inch from the zipper center, catching the under side of the zipper under your stitching. You will have to adjust your needle position again, this time, to the right.
Following your pattern instructions, complete the bag. Remember how I was nagging at you to be sure to measure carefully at each end of the zipper? See how the zipper tabs are now lined up perfectly on each end? Nice. Hope this was helpful. Don't be afraid of zippers!
