How can you stick posters?

So I want to put a bunch of posters up on my ceiling, but it's a popcorn ceiling. It's all bumpy and rough. It's not a flat enough surface to easily stick things to. I can't use tacks. Scotch tape is too weak. I'd prefer something that won't cause damage...

but it has to stick good, ive tried tape but it just doesnt hold ! its just cause i ripped pages outta magazines of pictures i like and i wanna put them up ???

I always hate when my posters flop down and dont stick.. so is there any household items that i can use other than tape or pins to stick in my wall.. i dont feel like going out to buy one now..l0l

I have many posters and I'm just wondering what I should use to stick them up. I'm also wondering if I should overlap the posters, or space them far apart or put them close together. Anything that will make it look like a real teenager's room. I am male...

i want to put posters on my wall without using: tacs; tape ; anything tht can be seen. -i just want it to look like that poster is just there. i dont want to see the adhesive.

We have tried drawing pins but they leave holes everywhere! And blu-tak leaves oily marks when removed! Any ideas of something that won't leave a mark when the posters are taken ...show more

Sooo my room is childish and I just found LOADS of posters of my favourite singers in my wardrobe, a few collages, photo frames, calendars and posters that are already on my wall. I want to use the posters like wallpaper, and stick them all over my walls...
