Can You Save Money With DIY?

I’m a huge fan of DIY. The remains of my various projects litter the entirety of the back porch. It’s fun to work on projects, and it’s a good way to bond with my son. The thing is, though, with few exceptions, I’m not sure I really save money doing it myself. Here’s why.
-
I tend to not finish things. However, unless I take the supplies that I bought back to the store, I’m out some bucks.
Sometimes I don’t even start things.
I don’t know how to do some things myself. Not every project works out. Like the jam-making project that turned into a gross lollypop-making experiment, thirty dollars later. At least it’s a good family memory. Sort of.
Even if the project works out, I may have only saved ten or twenty bucks by doing it. Considering that I can bring in $50 an hour tutoring, the time that I have spent going to the store for supplies, cursing my incompetence and ultimately completing the project may not have been worth it.
I get luxurious ideas when I DIY. Do I usually buy cashmere scarfs? No. Do I knit them? Yes. Nuf said.
