We buy all the tipis we hire out from mytipi.co.uk. The tipis they sell are of an excellent quality and they are a really knowledgeble friendly company to deal with. The canvas is 12/15 oz and they can also offer different coloured fabric to make your tipi unique.
Little details are really well thought out such as extra reinforcement of the lacing holes and at the crown of the tipi (the area where you tie the tipi to the lifting pole which is under the most stress)
Pebble ties/coin grommets offer a really authentic look and the style of the tipi being slightly taller than the standard squat sioux tipi creates a really striking presence.
We have tested them for many years and over hundreds of hires and we couldnt be happier with the quality and the service.
