I wil be doing a low level (tadpole) combined training show in about a month or so. I plan on braiding my pony, but I was wondering(Im new to the whole CT/dressage stuff) would it look out of place if I put the white braiding tape around his braids?
I wouldn't say out of place but something to consider...
I don't know what color your horse is, but just be aware that if your horse has a dark mane and you put white tape on the braids it makes whatever the horse is doing with it's neck very apparent. Any issues with bend, poll height, tension, etc. will be even more obvious to the judge. So, at lower levels it may draw too much attention to little errors!
I think the nice bands that are gold (since palomino) or silver ones are nice for a slight touch of color. I also think tape is a bit 70/80's. If you like tape, the other comments about really really needing it to be done correctly and straight are important....bad tape job is really bad to look at.
Old timer here, I came from a time when all manes at all levels were taped to show off the topline and accentuate the correct bearing in the horse, plus then you can braid (with rubber bands) in about 10 minutes start to finish with taping (12-15 evenly spaced braids). I love how it looks (as a judge). Dont care for the 25 braids a la hunter, unless thats what you are doing.
Do it if you want but it's not in fashion at the moment. I always kinda liked it and I can do the rubber band braiding Ideayoda mentioned very quickly and it looks nice, but I wouldn't be caught dead doing that right now at the bigger venues we have here.
