Just finished making my own Color Checker as per DrawMixPaint site. Last summer my project was to build self-watering containers. Spent about $100 bucks, grew $200 worth of fresh vegetables in pots, but wound up in the hospital with an $8000 emergency double hernia surgery moving pots and soil. So the Color Checker seemed like a safer “indoor sport” this year and today as I was making it my glasses band pulled out and broke so I incorporated that into a “wrist strap” for the color checker. All looks good and I am ready for my next painting project… *Note* Mark was right about holding thing upright and letting it cure properly. Does anyone have a suggestion / fix for epoxy that might have accidentally dripped onto my wife’s red Spanish tiles on our porch… lest I wind up in the hospital again?
