Step 6Making the Frame 1
Lets start with the hinge. You may be able to buy one that does the job but I made one because it was cheaper and only took 2 minutes.
Cut 4 6-inch lengths of wire and bend them into the shapes shown in the second picture. The loops need to be small enough not to let the washers slip through but large enough to allow them to turn on the bolt. The distance between the legs should be 1/2 inch and the legs should be parallel to allow strong fixation to the spars.
The third picture shows an assembled hinge. Make 2. Trim the bolt with the hacksaw.
The fourth picture shows the hinge bound to the spars, one short, one long. Cover the end of the spars in glue before binding with the cotton string, then cover liberally with glue afterwards. You don't want them to fall apart when you are wearing them. Make 2.
