Also check this link to see where I got the idea: http://blog.craftzine.com/archive/2010/03/pillow_chair_from_t-shirts_and.html
Step 1: Explanation
(12)Large T-shirts of strong cotton fabric, any thin kind will rip when your friends jump on it. Trust me.
Sizzors, yes I like to spell siZZors like that.
some type of paper for drawing the confusing pattern
chalk in different colors
sewing machiene with stong thread
some kind of stuffing for inside it, I originally used styrofoam balls from an upholstery store then switched to foam blocks (we'll talk more about this later)
You can see what they used on their site.
Step 2: Making the pattern
First you will have to make 12 "HALF wedges"
In order to do this you will make a pattern which is HALF OF ONE WEDGE (because 1/2 + 1/2 makes 1):
get a large piece of paper (I used news paper) measuring 30X20 inches and draw a line down the center.
On the paper start with a 60 degree angle at the top center and draw a soft curved line down length of wedge. They explain this better in the video http://www.generation-t.com/?s=bean+bag+chair
Step 3: Cutting it out
When you have your "purple" and "yellow" half wedges cut out, sew them along the line where they touch in the picture below with the "good" side facing each other. They unite to form a "HALF WEDGE" FINALLY!
**It is a good idea to go over this stitch twice because it might break open later when you or your friends are sitting in it.**
By "good" I mean the sides you want to show, the sides that have the pictures or jersey numbers or whatever else =)
After you have 12 "Half wedges" continue to the next step...
Step 4: Sewing
When you are sewing the top half wedge to the bottom half wedge go over the stitch twice and use strong thread.
Match the patters you like together, I put the Kool-aid man and the Locos moose together.
Step 5: More sewing
Basically after that you can fill it up with styrofoam balls or foam of whatever you think is best.
Remember to have sewn the stitches twice or it will break open.
I hope y'all enjoy this!
