Sewing (for repairs) is something that I’ve done sporadically over the years but admittedly have probably never known how to actually do it correctly; tending to stick some thread on a needle which is then haphazardly worked through some fabric and then in some way or another tied resulting in what amounts to some kind of messy knot that passes through fabric.
I’m now going to work on actually learning how to do it reasonably properly at least for the sake of sewing badges on uniforms and also to make some repairs such as a bag that I have from which the should strap keeps falling off (including after having it sewn back on at the dry cleaner several years ago).
One of the underlying skills would be tying a knot, where the instructions on the Sewing Directory seem able to be figured out and allowed me tie a fairly large knot which allowed me to attempt to sew the bag in need of repair (after several smaller knots passed through the holes).
My wife got my a small murse-y type bag many years ago, which appeals to my minimal sensibility since it can fit some of my mobile gadgets while being a notably smaller form factor than what would be required for a decent sized laptop along with accompanying wires and peripherals. I think the bag itself was fairly inexpensive and the shoulder strap came detached after a few years. The bag otherwise is still in decent shape and so at this point I’d be looking to reattach the strap by whatever means works sufficiently. Getting resewn at a tailor didn’t last long; I tried krazy glue out of laziness which actually worked better than expected (lasted a few months), and currently it’s using a mix of my attempting to sew it along with a fresh coating of kragle. My attempt at sewing was sloppy (it’s fairly awkward and also needs to pass through some fairly thick fake leather and canvas) but seems effective, though I think for my first attempt I used too large of a needle (ones that came with a set of thimbles I ordered and are probably all large enough to be for the type of work invites thimbles). I’ll probably iterate on this a bit, but may also look at something like rivets if it continues to come undone (before just giving up and tossing the bag).
