"A hobby is hard work you wouldn't do for a living." -Anonymous
"When a habit begins to cost money, it's called a hobby." -Jewish Proverb
"Making money is a hobby that will complement any other hobbies you have, beautifully." -Scott Alexander
"Up until recently, knitting was work. It was not a pastime, but a necessary chore that provided a family with clothing. If you didn't do it then your family just didn't have the things they needed. Sometimes I think about that and I wonder: Would you feel the same way about knitting if it was mandatory?" -Yarn Harlot
"Anybody who has ever tried knitting for money instead of love has noticed it would be very hard to earn a living that way. Knitting is handwork, and as such you would need to charge a small fortune for each creation. If a knitter were to be paid even minimum wage per hour, a knitted blanket could ring in at hundreds and hundreds of dollars. Weaving, on the other hand is wicked fast. A reasonably competent weaver can make a blanket in a single day. This brings me to the first rule of craft sale safety:Never put the knitters near the weavers. It takes more decency than most knitters have to not resort to violence when they find out." -Yarn Harlot
I think this is why I will always piece blankets and knit the little things.
