Is there an alternative to binding carpet remnant as a rug?

Recently moved into a friends basement to help with mortgage. Short of carpet it is a finished basement, just a concrete floor. I purchased some carpet remnant to cover part of it. I am worried about the edges fraying as it does not cover the entire floor. I know that having the carpet bound professionally is costly, and DIY kits are not available anywhere nearby, plus I have heard they aren t that great.

Does anyone have any tips to use on the edges of the carpet that look decent and prevent the fraying?
