Knitty, I hope you find the design…I searched the 'net yesterday- unsuccessful! I love my Folgers containers— use for so many things and would love to have the wrap pattern for them. I’m not smart enough to create myself!
Most computer "crashes" are due to components other than the hard drive (where all the files reside). A good tech can get all those files back to you. It is worth looking into.
Might be easier to measure your can and overlap, add length enough for Velcro and stitch on regular sewing machine? And I don't often switch to THAT machine for anything.
