In the project section sorval said she made the design with bmp. What do the letters mean. My mind is drawing a blank.

simple answer is: bitmap

Whay she meant to say is that she loaded a picture in .bmp format and digitized the embroidery herself with help of the software she owns. As a rule embroidery software uses .jpg and .bmp files. So a picture taking by your digital camera can be used in the digitizing program.

Here is what wikipedia says about a bmp file:
