Originally posted by kneemeister As an experiment I have replaced the door seals in one of mine with black cotton yarn, an entire roll can be bought at Jo Ann Fabrics for 5 bucks.
My Soviet rangefinder cameras (Zorki 4K, FED-2, and Kiev 4A) all have yarn seals. That being said, all three have slide-off full removable backs. Yarn seems to work well for that application.
Originally posted by kneemeister For the end seal you can purchase an 8 x 10 sheet of preglued felt and cut your own.
Caution that the thickness of that felt for the hinge seal is critical.
I appreciate the DIY approach, but while Jon Goodman still sells his most excellent custom kits with all materials in proper widths and thickness,* his product will remain my first choice when doing the seals. It also helps that I can't buy the materials for what he charges (~$10 USD, including postage).

* The strips for the rear seals are over-length and must be trimmed to size. This is done as a last step as they are laid in the slot. I use a pair of cuticle scissors. Jon usually includes one or two extra strips to allow for wastage.
