The best way to hang posters ...

[KiewiStyles]

on cabinet doors.

I thought magnets may work, but the door is non-magnetic.

What will work best: velcro, tape, etc?

Craft glue dots work well. StikkiClips work pretty well, too.

I am a die hard fan of the blue sticky stuff. It is reusable, and sticks to just about anything!! Course, I don't know the proper name of it, but I love the stuff. When I volunteered I always did the bulletin boards, and that was my favorite thing to use when you could staple it!

I use a combination of the poster putty (blue stuff) and stikki clips. The wax residue from the stikki clips comes right off with a little elbow grease and cleaner.

I have found that the blue sticky tack works so much better than the white or yellow. I know Walmart carries it.

I use packaging tape for everything - the alphabet, and number line have been up for 4 years in my room and have not come down yet...

I also use the blue sticky stuff, I put my stuff up when I started teaching and 3 years later I took it off. It leaves nothing behind and also helps keep the stuff up.

My vote is also for blue sticky tac, or the stikki clips. Those foam sticky tabs are also great!

I also hang things with book tape and hot glue, but I don't know if I'd use the two latter things on cabinet doors.

The parent-teacher store here in town has this stuff called mavulous tape. It's just white tape, kind of like medical tape, but it really holds. I didn't discover it until I was almost done setting up my room. so the stuff I first started taping off has been falling off, but the mavulous tape hasn't budged. I don't know if it's widely available or not but get it if you see it.
