The rectangles in question have 0 stroke size and no stroke color. It seems to me that if I snap several equal size rectangles to each other, they should appear (at least in output) as a single object with no internal boundaries. How can I achieve this result? I've tried grouping the rectangles (ctrl+g) and combining (ctrl+k).
My ultimate goal is to provide a clean .SVG file to a t-shirt company to silkscreen shirts for a school club. One of the students created a design in Paint which all the kids voted to use. However, the t-shirt company can't work with the original low-res raster art. It became my task to turn it into vector art. Since what the kids want is a very early '80s, pixelated, 8-bit sort of look, I decided to build their design (only partially shown in the image and SVG which are linked above) using hundreds of rectangles. I have faithfully recreated the original artist's design, look and feel, except for all the internal borders which I don't know how to get rid of.
