To count as a morsbag the bag needs to be –
1) made from repurposed / recycled fabric
2) have a morsbags.com or morsbags.org label on it
3) be given away free of charge
Additionally, it needs to be fit for its purpose, and the original purpose intended was to replace a plastic carrier (tote) bag. It therefore needed to be strong enough to carry your shopping.
I found a piece of beautiful yellow / orange / red organza a few years ago and made it into produce bags, but didn’t count them as morsbags. The topic was thoroughly discussed at various times between 2007 and 2009 on the old forum which is now read-only, but you may find it interesting to read. https://www.morsbags.com/forum-archive/viewtopic.php?f=3&t=467
While I think it is a great idea (and coincidentally, was discussing making them only a few days ago with, and possibly for, a relative who is associated with a farmers market …) I don’t think we could legitimately count them as morsbags.
