About 3 years ago, I bought a software program called Triangulations...
https://www.amazon.com/Bear-Paw-Tria.../dp/1936207168 and I've never looked back. No matter what the finished size is I can pull it up, print a page on my computer, sew the fabric to the page, cut it out and it's perfect!! If you think you're going to be quilting for a long time ahead this is one Must Have tool. Good luck with kit!
