Ok, the long-awaited tutorial is here. I am showing my methods for making the paper bowl. There are other methods. This is the one that works for me. It takes awhile to do a bowl this way, but it looks better when you are finished.
First, gather the things you will need for constructing the bowl. For this particular bowl, I am using grocery store ads (think Safeway, Albertsons, Krogers, etc). I have also used glossy junk mail and raffle tickets. You will need your paper, some means of cutting the paper, a short piece of doweling, a rubber band and tape. There are other things you will need later, but we will get to that.
I use a paper cutter, but you can use scissors.
I cut the paper into one inch strips. Try to cut the paper, so that you get the longest piece possible.
I put a small piece of tape on the end of one piece of paper. Next,I tape it to the short piece of doweling and wind it around to create a spiral. Once the paper is wrapped, I use the ruber band to hold it together. Next, I tape a few pieces of paper together and tape them to the end of the first paper I put on. I keep wrapping them around until, I have the bowl to the approximate size I want it to be. Keep the rubber band on between add-ons, so that it doesn't unwind.
After I have put on a few pieces of paper, I gently pull on one end of the paper to tighten the spiral. If you pull too tight, the paper will break. If this happens, just tape it back together and go on. After awhile you will get the feel for how tight it should be.
When I am finished constructing my bowl, it will look like a very thick pancake. Tape the edge down, so that it won't come apart.
I use my thumbs to shape the bowl. By pushing down on the inside, and gently pulling up on the outside, I get the shape I want. I leave the edge at the top a little thicker, so that it isn't sharp.
When I get to the size that I want the bowl to be, I decide on a border for my bowl. I use whatever pleases me at the time. I have used wallpaper, paper rulers, glossy posters, magazine covers, and the Sunday funnies. I put the border on until I have my bowl the exact size I want it to be. I tape it off, using a longer piece of tape. This is what holds it all together until it is glued and finished.
Next, you will need some glue, water, sandpaper, and acrylic sealer. I mix the glue and water, about half and half. I then paint this mixture on the bowl, inside and outside, allowing the glue to dry inside before doing the outside. It takes about an hour to dry.
After the glue has dried all the way around, I sand the bowl to make it a little smoother. It doesn't need to be completely smooth, just take out all the rough edges. I use a power sander, but you can do the same thing with a sanding sponge or some regular sandpaper. I use 120 grit.
After sanding, I paint on the glue again and let it dry.
The next step, you will need ventilation. Do this with the window open, or go outside. Any kind of sealer or varnish is going to give off some fumes, and you don't want to be sick.
I then paint on two coats of acrylic sealer, again inside and out. I sand between coats. When the whole thing has dried, I put on one extra coat of sealer on the top edge.
And there you are, one finished paper bowl. Let me know if you have any more questions, or if anything is not clear.
