Hi, I got involved with crocheting recently. I'm mainly interested in creating straw looking summer bags. For this I'm using raffia yarns and following youtube videos. The problem I'm facing is that no matter what I do, I cannot get my crochet nicely lay flat. It constantly either curls or twists. I've attached few pictures of the project I'm working on at the moment. According to the instructions, I'm supposed to use needles with 3.5 size. I've tried 2.75, 3.25 and 3.75 and couldn't get it lay flat with neither. When I use small needles, my work starts twisting from two opposite corners. When I use bigger needles, it gets full on wavy. Tried to stretch it horizontally and vertically but couldn't get it to work. The row that I've done las as half is with 2.75 needle and the one before that is 3.25. As after doing 3.25 for few rows, it started to extremely curly and I was hoping that 2.75 would tighten things up. But, as you can imagine this is getting more and more frustrating... Please help me! What am I doing wrong?.. (Also, pattern was able to reach the required dimensions with 8 rounds. I'm on 12th round and still not there... I think I should use larger needle for that, bit large needle results in worse waves than this).
