About
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
• Upload a pattern PDF and Patternizer fills in the details for you: title, designer, garment type, fabric, sizes, skill level, and more
• Paste a link to a pattern shop page and the details fill themselves in
• Share a pattern page from Safari or a shop's app straight into Patternizer
• Snap or upload a screenshot of a pattern
• Import a spreadsheet of patterns you already track
• Or type it in yourself. Your collection, your way
FIND THE RIGHT PATTERN
• The Pattern Picker walks you through who it's for, what you want to make, and what fabric you have, showing matches as you go
• Search by title, designer, fabric, or your own notes
• Star your favorites and keep a wishlist of patterns you want to buy
FABRIC STASH AND SEAMLESS DESIGNS
• Photograph the fabric you have on hand and track how much is left, whether it's prewashed and where it came from
• Keep the seamless design files you've bought, at full resolution, with the designer, shop and price
• Filter your fabric and designs by color
• Link fabric or a design to the pattern you plan to make with it
KEEP IT ALL TOGETHER
• Store the pattern files themselves alongside each pattern
• Save photos of everything you've made from a pattern
• Keep notes on your favorite fabric shops, printers and pattern designers, plus your own machine settings and techniques
• Track sewing to-dos with deadlines and photos
• Keep measurement profiles for yourself and everyone you sew for
• Customize the tags and categories to match how you sew
