I normally use a pop tab in the place of a split ring (keyring) so that you can secure the keychain onto whatever you want much easier. Then I attach the split-ring keychain to the pop tab.
Does anyone know if you could do this with a D-ring? I am clueless when it comes to key chains honestly. 😢 I want to make a pattern as a keychain for my Uncle's birthday although his birthday is in June, I just want to have it done so I am not racing to do it last minute. 🙈
