This is from a well known on-line printing company. They even supply a template if you want to make a bespoke design. PS .psd of course and CMYK colour space so will not open in Gimp.

The requirements are modest, Maximum size 30 cm x 30 cm (12" x 12") and 175 ppi That is sensible, it is printing on a fabric, it is never going to be a high quality photograph. Gimp works in pixels, so that resolves to 2100 x 2100 pix.
The crunch of course is CMYK colour space, Once complete in Gimp RGB colour space, you can change to CMYK, various means. There are on-line converters, Krita can do it and you see any color changes in the process, or command line ImageMagick.
First thing to do is get the actual requirements of the printing company you intend to use. They might have different ppi (aka dpi) requirements, they might accept RGB images, many do these days.
