In Sketch, I often have to make grids of items. These grids often include a border, which, to get it to appear as it would in CSS, requires that I create the grid and then subtract one for each row or column or both. It's effectively a margin of -1px between each item in the grid. Trouble is, neither Sketch's grid feature and Invision's Craft plugin allow a negative margin. Anybody have a quick work around for this? I love pushing pixels, but this is tedious.
