Welcome to a brand new forum!
Practically everything we discuss involves fabric is some shape or form and now when can go steps beyond things "machine embroidery".
I like to add machine embroidery to quilts and accessories as well as clothing and have a couple things posted in the Project Gallery where there are many, many great looking items....some include instructions.
To share my most frequent sewing tips:
(1) Open that instruction manual and test every feature of the machine - even if you have been sewing forever you may find a few techniques that you have forgotten or have never tried before! This is especially true with a new machine.
(2) Thread the machine with the presser foot up!
(3) Keep the bobbin case and race clean - heavy napped fabrics and quilting can "shed" a lot of lint and before you know it, the needle and bobbin case/race are making a strange noise. They are trying to work their way through drifts of lint and possibly a few thread snips. I have also found lint built-up in the feed dogs.
(4) No oil or lubricant unless stated in the manual that came with the machine as to when and where this is to be done.
There are many more good tips, techniques and suggestions out there - please join in!
