Making Papier Mache

I have been asked how many layers of paper to add to the balloon for the igloo project.

I used 3 or 4 full sheets of paper to cover the balloon each time so I can't say how many layers this would be. I let it dry completely, which takes about 24 hours! Then I added the same again - several times! This does take several days so you have to be very patient. After all, it is the preparation that is the important bit for everything. Yes - it is really boring too! It is well worth the wait. I keep going until I can't squeeze a dent in any of it. It should be hard enough to knock on.

I can't say how many layers to add. It depends on the newspaper and the consistency of the wallpaper paste. If in any doubt, try painting the whole thing with wood glue and let that dry. This will give it a reasonable amount of waterproofing too.

Of course, the thickness and the hardness will mean you might have a problem using scissors to cut it. I use very old scissors but I also use an old bread knife, like a saw, if needed. If you use a very sharp craft knife, please be extremely careful as the thing being cut is not flat and stable.

Please post a comment if you need any help.
