So I implemented this limit on my sewing. Not because I have to financially but because I had to emotionally. I am a saver, a keeper, a money-worrier. We (I) could easily spend triple that every month and it would not kill us financially. (We are lucky we are in such a good spot and I know that and am thankful.) But, I was always feeling guilty about my "hobby" so I self-imposed a limit on my spending. It is actually kind of fun. My rules are this: I get $100 a month, un-used money carries over to the next month, I can't use money for next month, no exceptions (yet). Here is my standing as of today: $43. It is only the middle of the month too. I had $65 from January that wasn't used but it is gone now. Yikes. It is this SWAP thing.
Wish me luck.
