Bog- How long does it take to do the hairstyles on your girls? Realistically for a first timer who has never attempted it?

Looks fabulous!
I am hair challenged so poor dd always has just a long braid. We tried the curly ponytail which looked cute but once got in the way during a back extension roll. Won't make that mistake again.

Last meet there was a professional photographer and dd had a braid across her face in most of the photos. Looking for a sleeker (though not too difficult to do) look. Thanks!
Well to be honest not too long, 15 minutes for Bigger bogs braids and bun. The spider web takes about 30 minutes.
Start with the right tools. A good brush that smooths hair into a ponytail, a tail comb (that is a comb with a long pointy tail) a spray bottle with water in it, a bottle of spray gel, good thick covered elastics, strong hold hairspray and sparkles!
Patience is the key. Practice before the meet, find a good show for DD to watch, as then the wiggling is reduced.
For Bigger bog's hair the first thing to do is to make a part about 1.5 inches back from the hairline, make it straight. Spray the hair with water and use the tailcomb to make this easier. Get DD to hold the hair forward over her face whilst you brush, spray and smooth the rest of the hair back into a high pony tail, secure with an elastic well. THat elastic will stay in the hair so make sure the pony tail is nice.
Then divide the front hair into six equal pieces, pull back one section at a time towards the ponytail and spray with gel, comb and then braid, when the braid is long enough put a small elastic in it, this elastic will be removed later, so it doesn't matter about colour etc. Braid all six pieces of hair, making sure they are pulled back towards the ponytail when you do it and that they are well sprayed with gel.
Now pull all six tiny braids back to the ponytail and secure them with a good, strong elastic, this will stay in place so use the right colour. Remove the six elastics from the tiny braids and smooth the end into the ponty tail.
Spray pony tail with water and with gel, make sure it is well sprayed. Hold the ponytail up toards the ceiling and twist it, as you twist the pony will pull itself down, use that to keep twisting until it forms a bun. Secure around the bottom with a third strong elastic. Spray with masses of strong hold spray, add a scrunchie and then spray with sparkles. Et voila!
The spiderweb is way more involved and requires a lot of patience and a tough scalp, you can do this the night before and it can last for over a week. Just google for instructions, they are all over the web (!).
