Pattern library app

Every pattern findable, readable, and marked up.

Downloaded PDFs, purchased patterns, bookmarked blog posts, and recipes in your head all deserve the same home. Purlsona files them together and keeps them useful — searchable when you plan, annotated when you make.

One Library For Every Kind Of Pattern

Patterns don't all arrive as PDFs. Upload the PDFs you own (one at a time or in bulk), save a link when the pattern lives on a designer's blog, or paste your own recipe as a text note. All three live side by side in the same library, and patterns you buy on Purlsona land there automatically.

Tags, Filters, And Sort That Fit How You Search

Add your own tags to any pattern — "gift ideas", "scrap buster", "next up" — then filter the library by tag, craft, category, or yarn weight and sort by recently updated, recently added, or title. The filing system is yours, not a fixed folder tree.

The Details You Check Before Casting On

Record craft, category, yarn weight, yardage range, gauge, needle and hook sizes, sizes offered, and a 1–5 difficulty on each pattern. When you're deciding what to make from yarn you already have, the answer is a filter away instead of a dig through downloads.

Mark Up The PDF Without Printing It

Open a pattern PDF right in Purlsona and write on it: a pen for circling and crossing out, text notes for size choices and modifications, an eraser and undo when plans change. Annotations save per page — and per project, so two sweaters from the same pattern keep separate markups. You can even export a flattened, annotated copy.

Purlsona vs the downloads folder

Your patterns deserve better than pattern_final_v2.pdf.

A folder of files can store patterns, but it can't tell you which ones fit the fingering weight in your stash — or remember what you changed the last time you knit one.

A PDF Pattern Organizer With A Real Reader

Purlsona's viewer opens your PDFs in the browser with zoom, page navigation, and fullscreen — then remembers your page, zoom, and highlight-bar position per pattern. Pen, text, and eraser tools write directly on the pages, and each project keeps its own copy of the markup, so the pattern stays clean for the next cast-on.

An Organizer That Follows Through To The Making

Organizing is only half the job. From any library pattern you can attach named row counters with linked repeats and row alerts, track your place with the highlight bar, and — when the pattern belongs to a project — log work sessions with a timer. The library is where projects start, not just where files sit.

FAQ

Direct answers for pattern organizing.

What is the best way to organize knitting patterns?

Keep them in one searchable library instead of scattered folders. Purlsona stores pattern PDFs, links to online patterns, and your own text notes together, with tags, craft and yarn-weight filters, and per-pattern details like gauge and needle sizes.

Is there a free app to organize knitting pattern PDFs?

Yes. Purlsona's pattern library is free: upload PDFs individually or in bulk, tag and filter them, read them in the built-in viewer, and annotate them — all with a free account.

Can I organize crochet patterns too?

Yes. The library handles knitting and crochet equally — each pattern records its craft, and metadata fields cover hook sizes as well as needle sizes.

Can I save patterns that aren't PDFs?

Yes. Alongside PDF uploads, Purlsona supports link entries for patterns that live on a website and text entries for patterns you keep as plain notes, so free blog patterns and your own recipes get organized too.

Can I tag my patterns?

Yes. Every pattern can carry up to 20 of your own free-form tags, and the library filters by them — alongside filters for craft, category, and yarn weight.

Can I write on my knitting pattern PDFs?

Yes. Purlsona's PDF viewer has a pen tool, text notes, an eraser, undo, and a palette of colors. Annotations save per page and per project, and you can export a flattened annotated PDF.

Can I highlight my current row in a pattern?

Yes. A movable highlight bar marks your current row on the PDF — adjustable in height and color, with a dim mode and an optional column marker for charts. Purlsona also remembers your page and zoom, so the pattern reopens where you left off.

Can I track rows on a pattern in my library?

Yes. Every library pattern can have row counters attached — multiple named counters with linked repeats and row alerts — so the pattern and the counting live in the same view.

Do patterns I buy show up in the organizer?

Yes. Patterns you purchase on Purlsona appear in your library automatically under a Purchased tab, next to your own uploads — no re-downloading or importing.

Can I import patterns from Ravelry?

Ravelry doesn't offer a pattern-library export, so there's nothing to import directly. Pattern PDFs you've bought there can be downloaded from Ravelry and uploaded to Purlsona like any other PDF — and Purlsona does import Ravelry yarn stash exports.

Is Purlsona's pattern organizer really free?

Yes. Uploading, tagging, filtering, reading, annotating, and row counting are all free with a Purlsona account — the library is not a limited trial.

Do I need to install anything?

No. Purlsona runs in your web browser on any phone, tablet, or computer, and your library follows your account across devices.

Give every pattern a home.

Upload your PDFs, save your links, tag it all, and find the right pattern the moment the right yarn shows up.
