As you may remember from my posts last year, I made zippered bags for everyone in the family this year for Christmas. Two of the gentlemen in the family wanted a bag, but not the ones I made. They are both avid cyclists and wanted a bag to attach to their bike big enough to hold an extra pair of sunglasses in a case. Their preferred material: vinyl. They also each wanted the bag to attach to the cross bar of their bike and they didn’t want the bag to swing when the bike was in motion. With that information, I went home to see what I could do for them. I found a piece of marine vinyl big enough to make both bags.
I used the roller to press in the hem since you cannot use pins on vinyl. Once the hem was pressed it was time to insert one side of the zipper. The zipper is intentionally much longer than what was needed to make working with the bag’s construction much easier.
I marked the back of the bag for the 1” drop I wanted for the zipper, so the zipper would not be directly on the very top of the bag. This decreases the stress on the zipper over the life of the bag. After marking the line, I used a 1” wide ruler laid along the line and then I folded the vinyl over it to create a crease.
Next item in the process was the addition of the Velcro straps to hold the bag to the bike. I used 2 straps on the top of the bag and one on the bottom, off set to the right. This was to hold onto the bike’s diagonal bar to keep the bag from swinging on the cross bar while the bike was in motion. I overlapped the straps ½” and used the four way stitches on my machine to secure them to one another. I used my plastic stiletto to mark the strap placement on the front of the bags.
