I'll also start checking all the references in this thread for info and assistance.
Thanks for the inspiration.
way to score!
Start simple. flat square things with out curves or weird angles. Pick projects that are not as visible for your first attempts. you will get better and improve your results!
Go slow. measure twice (or three times!) and cut once. use an old sheet for practice especially setting zippers. The zip can be set into scrap and ripped out until you have it down and then your real fabric won't get ratty looking.
Use long stitches that are easy to pull out to begin and then when you have it all done correctly go over it and stitch with a shorter stronger stitch.
Plan on being patient and ripping a lot. Get a ripping tool or three. they are cheap and make an annoying task got faster and easier. using scissors to rip seams is not fun.
canvas and sail shops are pretty generous with their scraps and will let you have their bin bits to practice on.
When you start making mistakes stop. you are tired even if you don't know it. let it rest and come back to it it will go better later on. A sewing machine is not a hammer and needle is not a nail! and sewing is more fatiguing than newbies realize.
make sure the light is good and that you have everything at hand in your work space.
remember that it is NOT rocket science and you can do it. enjoy the process.
and did I say plan on ripping a lot?
Have fun! and good luck!
