I have an acquaintance who I know made ~$1500 in 2 weeks, just after work occasionally. She had been on the site already, the only reason I know the amount made during that time is she did it as a fundraiser and donated it all to a non-profit. I'm sure it's a distribution with a long tail, but I think it's probably easier to have a side gig on OF provide you with a little supplemental income rather than Etsy.
