You do not have to use obijime with yukata obi but obijime tie can be a lovely accent! You can use more than one obijime, and obijime can make whimsical effect too!
You can use almost anything as obidome! *lampwork big bead(Tonbo dama) is very popular. *My mother's old broaches could become nice obidome too! *Metal, ceramics, plastic, ribbons, buttons...old accessories can be charming obidome too!
As I mentioned, my hands are not clever (and do not have many good ideas!) but still there are a lot of possibilities with yukata obi bow. Even your yukata obi is a simple one, you can fold, add something and create charming front style! I hope you enjoy the photos. These are very easy! You can just fold to make different look!
