Abstract: A process of marking fly fishing lines includes the steps of selecting a heat shrinkable tubing having predetermined shrinking temperature characteristics and marking the tubing with a size coding positioned to allow the marks to be cut off to indicate any of a range of fishing line sizes or weights. The tubing is then cut to form small sections with the marking thereon and may then further be cut to remove marks to indicate one size. The tubing is slipped onto a fly fishing line and immersed in a heated liquid, such as water, or water having salt added thereto, to shrink the tubing onto the fishing line without damaging the fishing line.

Abstract: A method of making a fishing line indicator for nymph fishing uses a thin sheet of flat closed cell polyethylene foam having a plurality of hemispheres formed thereon to which is applied a rubber based adhesive to one flat side thereof and then covering the adhesive with a protective covering. A fluorescent coat is applied to the other side of the sheet having hemispheres thereon and a plurality of fishing line indicators are cut from the sheet, each including two hemispheres.

Abstract: A buoyant fishing line is produced with foamed core surrounded by a filamentous line with or without being coated with a flexible surface layer.
