Good morning wmcunninghamii,
Well, if you're going to get a machine, all those projects you mentioned will be more within your grasp. We have made cushion covers, a downwind rain awning (actually different ones on different boats),
weather cloths, boom bag (on a 17 foot boom),
hatch dodger, and
dinghy chaps....and also sewed wrap-around skirts for locals in far off places. My background for that was sewing
clothing for my
family. [I bought a 2nd hand
SailRite machine, from another cruiser, and making just the boom bag did more than pay for it.]
One thing I did learn, is that if you are willing to use zig-zag stitches, not only is it strong, but it is way easier to rip out when/if you make a mistake. That said, I use zig-zag to reinforce seams, now, mostly, preferring the look of the straight stitch. Yes, use basting tape, but use it next to but not on the seam line. Use the hot knife on
acrylic canvas, for cutting, so it cannot ravel, because candeling seams is a nuisance. It is better to allow the time for hot knifing.
Finally, I became enamored of the
concept of WeatherMax because it was half the weight and
price of Sunbrella. However, in 2 years, the dark red had faded to what to me was an ugly color. I don't like to replace things for appearance only, and I wished I had used Sunbrella again. We used the medium gray WM for the
dinghy chaps, and the color it fades to was not objectionable to me. It is something to do with the dyes. If you are so positioned, sometimes people give away their old Sunbrella
mainsail covers. They are an excellent source of material for
cockpit cushions, if you care for the color. It's a great source for things like dinghy tank covers, o/b covers, etc. My kind of recycling, but you have to have a thick skin.
It is a kind of frugality that seems generally unpopular in the community.
