I usually make 4 oz at a time so I double this formula. However, I have a hard time deciding whether to add 1, 2, or 3 % for the flavor. Not sure if 1% is strong enough or if need up to 3%. I have made lip balms that did not hardly taste or smell, and made some that had too much. Be nice if the flavor oils label would tell you what per cent works best in 2 oz or something. ?
