Where can I get my own designs printed on bedsheets and or bolts of fabric?

I found a company that will print your designs on a variety of
fabrics, but there's one problem: the inks are not washable, so this
would not be suitable for sheets.

Have you checked with local silk-screening shops in your area?

I am a screen printer and what you should look for is a screen printer
that specializes in wide format sublimation dyeing. Sub dye will allow
you to print full color, but you are limited to fabrics with a
synthetic content.Totally washable.

Hi there,
Yes, I have checked in my area, which is Las Vegas. I found companies
that can print on larger format, but only up to around 3'x3'. Also,
since all I have found are companies that print digitally, it doesn't
retain color for vary long. I have found a place in Maylasia, they
manfacture, print, sew bed linens. I don't undertsand why this is so
difficult to find. I walk thorugh Wal-Mart or Target, and there they
are!! it's driving me nuts! If you have any more info, I would be more
than happy to tip gernerously!
Thanks,
Angie
