I usually knit I cord for drawstrings but honestly find it very tedious. I would like to crochet a drawstring instead. I can do the simple chain BUT it seems very tiny/thin. How do I make it a thicker, more substantial chain? Any tips from someone who knits well but knows little to nothing of crochet? I only have 2 hooks, BTW - G and D. I've been using the G since it's closer to the size 8 I used to knit the shorts.
