I am about to get my first ever sewing electrical device, and have never used one before.
I am going to attempt to start making infant things, slings/booties/dresses etc.

Any advice for me?
How long does it take to get hold of a basic understanding of things close to seams, good finishes, the similar to?

Advice appriciated, thank you.
How to bring back rid of these gnats?
Answers:    The best way to learn is by taking a class. Large textile stores that also sell sewing machines usually offer classes. Also when you buy your contrivance they should offer you a class so you have a firm elucidation of the various features of your machine and instruct yuou on things approaching bobbin tension, attachments, changing the foot etc.

Your local grown ed program may offer actual sewing classes, such as adapting a outline, tailoring etc.

Good Luck!

PS (it is beginning sewer, if you were doing it for a trade then you would be a seamstress LOL)
Has anyone see a snow shovel that's...
It is seamtrist. not a sewer as in city sewer. Now, be lenient. It is like riding a bicycle. It will take practice to achieve the hang of hems, stitches and especially gathering. Don't try to sew so fast. That was one of my problems, considered necessary the machine to go too speedy. Goodluck, you will do fine.
