Quick start

  1. 1. Build your stash

    Open Stash and add what you own — pick from a brand catalogue or add a custom thread.

  2. 2. Create a project

    Open Projects → New, add the threads your pattern needs and set the quantity for each.

  3. 3. Check your shopping list

    Flossom compares your stash to your projects and tells you exactly what to buy.

  4. 4. Stitch and update

    Mark threads as you use them — your stash and shopping list stay in sync automatically.

Features, section by section

Your Stash

Your stash is your personal thread drawer — every skein, bobbin and loose strand you own, all in one tidy place.

Free
  • Add unlimited DMC and Anchor threads from the full catalogues (yes, even discontinued colours).
  • Create custom threads for hand-dyed or off-brand floss.
  • Add notes and tags to any thread (e.g. “gift from Mum” or “low stock”).
  • Adjust quantities as you stitch — Flossom remembers the rest.
With Pro
  • Unlock all 54 extra brand catalogues — Madeira, Venus, Weeks Dye Works, Kreinik and more.
  • Use the colour picker and live camera scanner to identify thread colours on the fly.
  • Find cross-brand substitutes when your favourite colour is missing or discontinued.
  • Export and import your whole stash as a CSV — perfect for backups or sharing.

Projects

Projects are where your patterns live. Add the threads each pattern needs and Flossom tells you what you’re short on.

Free
  • Track 1 active project at a time.
  • Add the threads your pattern needs and set the quantity per thread.
  • See at a glance which threads you already own and which are missing.
With Pro
  • Create unlimited projects — keep all your WIPs running side by side.
  • Attach pattern photos and work-in-progress snaps to each project.
  • Import thread lists straight from a screenshot or photo — OCR does the typing for you.
