Patternizer
Read full descriptionHide full description
Made by Jessica, a sewist who got tired of digging through folders of PDF patterns and screenshots. Your whole pattern stash, organized, and finally easy to search. Patternizer is a home for every sewing pattern you own or want. Stop digging through folders of PDFs, bookmarks, and paper envelopes. Add a pattern once, and you can find it again in seconds. And stop buying patterns you already have. Before you check out at a pattern shop, search your stash to see if you already own it, or one that's an awful lot like it. Patternizer also gives you a heads-up when a pattern you're adding looks like one already in your collection. ADD PATTERNS THE EASY WAY β’ Upload a pattern PDF and Patternizer fills in the details for you: title, designer, garment type, fabric, sizes, skill level, and more β’ Paste a link to a pattern shop page and the details fill themselves in β’ Share a pattern page from Safari or a shop's app straight into Patternizer β’ Snap or upload a screenshot of a pattern β’ Import a spreadsheet of patterns you already track β’ Or type it in yourself.
