Shayla, I am very sorry for your loss ((HUGS))
Kellie, you may want to get a consult for ergonomic use of canes - they shouldn't cause carpal tunnel if you are using them correctly. I had to practice quite a lot to get the hang of walking properly with a cane, because of my coordination issues.
I could never propel my own wheelchair so no advice there, other than getting a motorized one. You may be able to find a good deal on a used one, if price is a factor. (I bought my push chair for $50, almost brand new - usual price for this model is $300-400.)
Elena, you can download your Etsy listings into a spreadsheet:
https://www.etsy.com/ca/help/article/338so I just keep that one separate from my website listings. I don't have any other major sales channels where I need a stock of unique items premade, though, so it is not as hard for me as some of you.
My items are all small, so I just keep them sealed in individual plastic bags, then organized in labelled (used) bubble envelopes. Everything is in a filing cabinet, & my website has a separate drawer from my Etsy shop. But that wouldn't be as easy to do with larger items, of course.
