Quick facts
A DST file is a set of stitch instructions: where the needle goes, when to trim and when to change color. It isn't artwork you can resize like a vector. Scaling a DST by more than about 10–20% changes stitch density and can ruin the sew-out.
DST stores color changes but not thread colors, so machines show default colors. A stitch-out sheet tells the operator which thread goes on which needle.
