in an open box

for patterns that I download or tear out of books I store this way and break down by applique, pieced, log cabin, stars, etc. the purchased patterns I store them in a 5 drawer bin - I have more patterns than I could make in a lifetime but I see inspiration in them all

hubby brought me an old metal filecabinet from his work, four drawers! it works fine for me

I put my patterns in a plastic sleeve and place them in a notebook. I have a separate notebook for crib/children patterns. Every couple of years I go through the patterns and trash some of the patterns, those I have had for years and didn't make, changed my mind on the pattern for whatever reason. I do group the patterns together, like all the star patterns together, etc.

That's the way I store mine also. I put a tab on each pattern with the name of the pattern and store them in alphabetical order within the notebooks.

I store mine in a Joann's box in which they can be filed sideways.
They are filed by type. E.g. redwork, placemats, repro quilts etc.

I use the 6" x 9" manilla envelopes, for the patterns with torn envelopes, I also use quart size ziplock (although you can't close them, the patterns are still protected). But I think what your asking is where do we put them? Right? I found years ago a fabric store going out of business and bought one of there pattern cabinets, and any filing cabinet will work too. Check your local thrift stores: salvation army, value villiage, or goodwill, I was also able to pick up 2 filing cabinets (the wider ones) at the local value villiage for $10 bucks each. Try craigslist too, businesses selling off there filing cabinets.

i have three ring binder with plastic sleeves and have a pattern on both sides and then i can go through it and pick out my pattern.

I have so many patterns I use the large plastic file boxes,
one for quilt patterns (on my third one) one for doll
clothes , one for craft items. I stand them up until they
are full, then put cover on and store on a shelf.

I use 3 ring binders for loose pages and a file cabinet for packaged patterns. Sewing, Crafting, Quilting, Miscellaneous. Current projects I keep in those cloth type bags with fabric, pattern, embellishments,etc all ready to sew. These hang from a pole in the corner of my sewing room where I see them every day. Gets me motivated quickly.
