This was great fun to do for both of us...!
It took about 45 minutes and 120m of ducttape to tape her body; then she walked around, rolled on the floor (lots of floor mats there) and got petted for another hour.
Don't put ducttape on bare skin - and of course hairs - , e.g. use old pantyhoses, leggings, gauze bandages.
Don't put ducttape on under tension, where it can restrict breathing or blood flow! If you don't know what this means, don't do it at all! You have more control over tension if you use precut strips of tape, or roll the tape off before application.
Don't put ducttape on while under influence of alcohol or other substances, both taper and tapee.
Don't put ducttape on without testing for allergic reactions beforehand. Work your way up from smaller areas, try a ducttape gag first etc.
You don't put ducttape on without a plan of how to get the person out safely and as fast as possible if need arises! Have rounded safety shears or other safe tools handy and practice on ducttape beforehand. Don't use fancy, impressive knifes!
Don't put ducttape on without regularly checking the psychological and physical well-being of the taped person; this includes e.g. claustrophobia, breathing difficulties, dizzyness, overheating, dehydration, numbness or pain of limbs and fingers. If this occurs, get them out as quick as possible.
If you want her to crawl around either have soft padding on the floor or taped into the suit as pads for knees and elbows.
Talk beforehand about what you plan to do. Start small. Work your way up. Use your common sense. Have respect for and always take care of your partner!
The head/hood is a critical area/piece and was done separately beforehand and laced on later on - you can see the lacing hanging down.
In an emergency she could have gotten out of the suit within 20-30 seconds using safety shears.
