I personally think opening one or two comission slots would be a great idea! It would help with income and give people a chance to get something they'd love to get from you similar to a YCH they might have missed

Agree with Ryv3r, though I would add that if you are nervous about reopening then you can put some restrictions on what you'd want to do for these commissions. That way you can have control and stay within your comfort zone. I may be interested in a commission idea but I'd want to wait and see if any other people have ideas first.
