I have found that taking a picture of your machine setup
(stitch length, and/or any changes you made for a quilt)
helps if the machine accidentally looses power.
This has happened to me several times.
Use my cell phone to "stage" fabrics that I am thinking
of using together to get a feel for how they look.
Take pictures of ends of bolt info in case I run out and
need to to (hopefully) buy more.
I KNOW there are more ideas, but can think of them just
yet.
