Hi
For tanning parties I send out a small bottle of solution to the hostess along with some q-tips for patch testing any newbies - usually 2 weeks before.
On the night, arrive and set up in a seperate room. I do this because all though most of the group will be friends, they are generally not too happy to be naked in front of one another and prefer privacy for the actual tan.
Go through the consultation if they haven't already filled a form in, make sure they sign it and have had their patch test previously.
Next, start tanning, generally I sort out how many 8%/10%/12% clients I have and try and do it in order so that you are not forever changing your solution.
Afterwards, pack away, then give out all the aftercare advice alongwith your contact details in case of any problems.
Try and book more parties if anyone interested! Offer retail items if you have them.
Collect the money in and go home! HTH
