I thought that $300 knee pad upgrade was a waste until I finished a whole week without back pain.

I was using the wrong brush for shellac for years and didn't know

I was finishing a walnut table for a client in Boise and the finish kept getting these tiny bubbles no matter how careful I was. My buddy came over, looked at my $20 synthetic brush, and just laughed. He said shellac needs a natural bristle brush because the alcohol in it makes synthetic ones act weird. I switched to a cheap ox hair brush and the next coat went on smooth as glass. What other basic tool mistakes have you guys made that seem obvious now?

I saw a facialist in Miami use a technique I thought was totally wrong

I was at a big skin care show in Florida last year and watched a demo where the esthetician used a high frequency wand on a client with active acne. I was taught to NEVER do that. She explained she uses a very low setting and a glass electrode, and it actually calmed the redness down in minutes. It made me rethink my whole approach to inflamed skin. Has anyone else tried this method on breakout areas?

Just logged my 500th hour on a single underwater grinder motor without a rebuild

After a year, my room temp ferments are still perfect

I think everyone stresses too much about keeping things cold. My basic setup has made great pickles and kraut without any special cooling gear.
