Enlarging a pattern

Does anyone know how to enlarge a pattern? I want to make a 3X from a pattern that only goes up to L. The main problem is the armhole shapings and sleeve caps shapings.

One way to do this is to look at the difference in stitch numbers between sizes. So for instance, the CO numbers would be 8 sts difference, you would maybe want to go up 3 ‘sizes’ from the largest given, so you would CO 24 more sts. It should work similarly with the arm shapings. Each size starts with a different stitch number and you do a different number of the decreases depending on the size. See if that would work out at your gauge so you’d end up with the right measurements.

Thank you very much. I will try that. :slight_smile:
