So I bought this pointed crochet hook and tried it out on a cheap H&M tank top. Used thin cotton crochet thread and changed to an ordinary 1.25mm hook after doing the first round of sc with the pointed hook, working into the fabric. Then I just made it up as I went along, round by round. Should have written down the pattern, can’t remember exactly what I did now. Also had to work decreases every few rounds to stop the lace from curling and get it to lie flat. Very pleased with this bit of upcycling! Definitely looks more expensive than the $4.99 I paid for it!
