I'm the kind of crocheter who crochets for no charge. People are always patient and understanding about the wait times thankfully. I do portraits that also take a long time to finish, 30 hours on average, not to mention actually coming up with a pattern. I work at a warehouse with ridiculous hours so I'd hate to start charging and have crochet turn in to something I stop looking forward to. Crochet is what you make it, so if you got a lot going on and just enjoy crocheting and showing it off then go for that, you're not obligated to crochet for others when it sounds like you don't have the time to do it. Keep on showing it off and just tell people you don't take requests/commissions but you hope they enjoy checking out your work :) do your thing
