Casi,
I use my embroidery machine for MANY things from making quilt labels,
designs on baby bibs, to FSL (free standing lace) such as book marks &
earrings/pendents, monogram items.
A couple weeks ago I spilled some iced tea on a white top I was wearing.
After getting home and pre-treating the stain, repeatedly even and washing
the top there is still a light "off" coloring. It's not a big spot but I KNOW it's
there so I am going to put an embroidery design over the spot to "hide" it.
Hardest part is deciding WHICH design I want to use. Since it is a top I
pretty much wear year round (as an "under" shirt with long sleeves in winter)
I want to do a design that can work for any time of year.
Do not worry about what "others" may think of how/what you use your embroidery
machine for. It's part of your sewing HOBBY just run with it and have fun.
