I too, like Geek made myself a data sheet in MS Word. I have had to change it from time to time, but no big deal. I print them out about 20 sheets at a time and put them in a 3 ring binder. A basic candle test sheet sample can be found on www.candlecauldron.com. When I test a new candle, I hand write the info on a seperate data sheet. I also put little stickers on each candle sample including F/O scent, wax type, wick type and date made for quick reference. After I've done a burn, I go back to my data sheet and write down my results, such as color, frosting, throw,wicking and burn quality. I'd be lost with out my sheets. When I'm studying and taking note on Candle Tech, I have a spiral notebook with dividers separating different information like containers, wicking sizes, F/O and wax types supplies and tons of other stuff. My DH laughs at me and says that it looks like I'm studying for final exams when I'm studying and taking my notes on CT. I've learned so much on CT and thanks to all the wonderful people who ask questions and those who share information. For my People Candle Testers, I make a spread sheet in Excel listing all the candles scents and ask questions like, how was the throw, F/O scent, wicking, burn/time, mushrooming, melt pool and if they liked it,loved it or hated it. I give them a paper copy with their candles so they can fill it out right away after burning a candle. Cause sometimes they forget what was what. That's about it! Have fun and keep notes!
