A couple of ideas we include in our bondage play.
First, we use coloured self-adhesive bandages. We find they're not particularly reusable, but very cheap from the medical suppliers we use (we buy some stuff for first aid rather than play reasons!). They are breathable for the skin and the bandage sticks to itself but not to skin, hair etc. Need to be careful around the neck as they tend to tighten a little when on.
We buy 10 cm wide ones in red, green or blue from www.firstaid-direct.co.uk (click on first aid for domestic use, then bandages and you'll see them down the bottom of the page - 'Flexi Wrap Cohesive Bandage' at £1.99 per roll) - takes quite a few rolls if you want an all over wrap (we normally leave 'interesting bits' unbandaged!).
You can get narrower widths in blue only from www.firstaid4sport.co.uk (click on 'strapping and taping' and then 'cohesive bandages') and www.hygienefirst.co.uk have the bandages in different widths but only in a tan colour at the moment (click on 'wound dressings' and 'Tan Cohesive Bandage' is at the bottom of the page)
Secondly, we use extra large tights for bondage - a single leg being used for both legs, and again a single leg used over the head and pulled down over the upper arms and chest. We sometimes (not always for bondage) use open crotch tights over the arms and with the head through the crotch part, often with a matching pair worn on the legs, but sometimes like 'Jester' tights (tights with a different colour for each leg - we bought from eroticclothing.co.uk who have a sale on a couple of colour combinartions at the moment, www.blushbabe.co.uk and www.innerbabe.co.uk have some too and more combinations in multiple quantities at www.wholesale-tights.co.uk )
hope one of these ideas helps !
