As a Glass Artist, I too used to do a lot of in person shows, and had to switch gears.  I am selling online with Etsy.  They do take a chunk out for their fees and advertising, but it is sales I would not have had otherwise.  

There are many virtual shows, and actually I was surprised as to how my art has sold this way because photographing glass is extremely difficult to capture the depth.

On another note, Uline (packing materials) moved to Lacey WA and you can order all kinds of sizes in boxes etc and pick them up directly to save shipping costs as that can be incredibly spendy.  If you order less than $300 in product they tack on $25 but it is still cheaper than having them shipped.

Another option is to find Co-Ops and small stores that will take your product on consignment.
