I am looking for a crochet mathematical formula or a calculator/ generator. I found a pattern online that I want to do but I want to make it twice the size. I haven't had any luck converting the pattern to fit my size requirements.
Here is the link to the pattern I'm working on.
I've finished up to Step 10. Converting Steps 3- 10 is pretty simple to make it twice the size. Steps 11- 20 I work 120 sc into 20 rounds. Steps 21 and onward however I am having trouble converting. Please help. I'm not very good at math.
You could try this waist shaping calculator. I have used it to change waist, bust, and hip measurements. You may have difficulty making this much of a size change, but this should help.
