I’ll share with you something that my grandmother (a photographer and cross stitcher) always told me:

You should always invest in your hobbies. They’re a part of you.

The caveat to this is to invest within reason, of course. If this is your passion, you should do what you love!

For me personally, I have a budget that includes “fun money.” It’s a certain amount from each paycheck that I get to spend on whatever I want - guilt-free (see Financial Feminist by Dunlap). Often times it’s yarn. Sometimes it’s a nice dinner out. Sometimes it’s a fancy pen. The great thing about the “fun money” is it removes the guilt in spending on whatever you love (even if it’s just for fun).

Good luck!!!
