Congos are my biggest problem. They're painful to rip apart, and involve more maintenance (even after cutting). New, small dreadlocks are usually the ones with this problem. I find that this is a big problem for people with lots of dreads (more dreads = more maintenance). I have heard of people sleeping on silk pillows. Silk prevents friction between dreadlocks. I sewed myself a scarf for sleeping. With my dreads wrapped in silk, they stay tight after maintaining and reduced congoing BIG TIME.
I will be selling these scarfs for $20 soon. I know $20 seems high, but silk can run up to $10 a yard at the fabric store. I will be posting a picture soon. If anyone is interested in buying a sleep scarf, please let me know. Im not sure how it will sell, and I don't want to invest money in silk if they wont sell. Much Mahalos.
