While I am not great with Inkscape the one bit I do know.......there is a box near the bottom that can be changed to "all" files. That seems to help me when I lose patterns.
I have the Elipse brand respirator. I have vacuumed out the filters. Changed them maybe every 9 months. I saw a recent video where the wearer cleaned it with an alcohol wipe. Makes sense to clean regularly.
Upon occasion, if Steve did this as a second pattern, it doesn't seem to get into the catalogue. He has said in the past that he puts them up on Pintrest so you can see the thumbnail pictures there.
Thank you for the kind words.
I don't see them very often but when I do I am in awe at the majesty of them. Good luck with getting your shop set back up. Hopefully it is smooth cutting from now on.
