Shaun - yes the black in the pattern are the parts to remove. Some are just lines so you need to cut up one side of the line and down the other side. Then put a dark colored backer behind it. People use black card stock (but that can fade over time), black cloth, foam sheet, or a flat black painted wood. Try not to get glue squeezing out into the pattern when you put the backer on.
If you want to frame it, make the frame yourself or size the overall blank to fit in a commercial frame (8x10 etc). If you have no other drawing tools, MS Word works well to insert the pattern gif then re-size it as needed. I did not add any boarder around the original, but here's one with an 8x10 format. The dashed outline is just a guide for placing it on the 8x10 blank.
