I don't have too much room. Also, too many binders would be too much for me.
I scan in the patterns and instructions I want to keep and put them in my quilts scanned files. These are backed up without my trouble.
This saves me a lot of space. I can pass on the magazines without having them mutilated.
When I want to look all I have to do is turn on my computer and go through my files. Much easier to do that trying to sort through big heavy binders.
If you really want to go OCD you can put just the complete quilt pictures in one file with proper labeling and then put the quilt picture and directions in other files ... like a file for curved seam quilts, a file for applique, a file for fusible, etc.
This way I also have more room for - gasp - fabric!
