Hello darling! The type of knot you can make completely and totally depends on the length, stiffness, and thickness of the obi you use. The knots that are worn with furisode are often so complicated, they take a lot of skill to get it right. They most likely will require the assistance of another to accomplish it and make it look right. ^^ More complicated knots require extra obijime to keep it all together. ^^ Sometimes you can find tutorials for more simple knots, like box knots, butterfly knots, so on and so forth, however the complicated knots may be harder to find tutorials for. ^^ I'll help in whatever way I can though, to help you make your beautiful ensemble ^^
