I’m pretty sure it depends on who you’re working for if you need those crafting skills or not. However, I do believe it will give you a competitive edge. And in the case of freelance furniture building, unless you get somebody to do the actual work, the skills are obviously indispensable. My recomendation is that you should still try and learn the skills because I dont think you will lose anything if you do (see if there isnt any local programs that will help you with that). Besides, it might be a good hobby and/or open doors to other professions that you may be interested in. Ask professionals about your concerns, Im sure they will help.
Best of luck!
