So I've got this chipmunk onesie that I really love - great for parties, festivals and chilling at home. Unfortunately the other year I managed to burn it in several spots when holding a sparkler a bit too close (wearing this around fireworks was a dumb idea - I was slightly drunk at the time).

I'm wondering what the best way of repairing this would be? should I pinch the holes closed and just sew them shut? Or cut out a slightly larger slit to sew across a neater edge?
