Actually we are all in that same boat!
Bad hands and not the kind of cash to justify a HD Sewing machine. I have found that with several of the tricks already mentioned here, that all but the most heavy duty sewing can be accomplished, sewing like a pair of boot soles or heavy saddle parts stiched together, can best be farmed out to someone with a HD machine.
Hand sewing, or saddle stitching is by far the best way to go for strength and lasting work. Practice is what is needed to learn to sew a nice even stitch, your work is best when someone sez "Is that hand stitched?" It took me a long time of crooked joints and lines before I finally found the rythm and got it down to where it is presentable. Just like shooting, ya got to practice!
I use a diamond awl for poking them holes and sharpen and strop it before and during the sewing chore. I recently cheated and used a pin sized drill in a dremel tool for a heavy 1911 holster
due to my hand strength and arthritus.....needless to say I've gotten over that hump and will do it again! One of the things that I now do, is to glue my surfaces together with Barges or something like that to hold my two edges together, for punching and lacing and or sewing.
One last thought that was mentioned by someone is to buy a book and read it BEFORE you start, to save time and possibly a nice expensive piece of cowhide!
