Lately I've been experiencing a low-grade frustration with my bicycle pannier which has turned into a bucket-o-chaos. This instructable will document my first attempt to straighten it up a little.
Step 1: Materials
stretch elastic ($2.79)
sticky a** glue
clothespins (as clamps)
sewing machine, thread
Step 2: Stiff interior
I cut three such shapes out and glued them all together with wood glue.
Lay the glued boards down on some place flat, like the floor, lay a heavy object on top of that to keep it flattened while it sets up.
Step 3: Fabric shell
Add a half to 3/4 inch margin all around to be the seam allowance
Step 4: Elastic grabbers
Cut out strips of elastic to go along one side. I alternated the elastic with one inch of exposed stripes, measured out with a ruler.
Attach the elastic to the seam along one side where marked.
Stretch the elastic across, lining up the ends with the markings on the other side seam. Sew those down.
Step 5: Pockets on the other side
Attach those to the side seams
Step 6: Sew thick envelope together carefully
Invert rightside out
Try fitting the cardboard into it.
