Chair!

what you'll need:

chair

screw driver 

garbage bags

primer

paint

hot glue gun and hot glue(or stapler and staples)

fabric

start with an old chair that needs some more oomph

D.I. is the best place to find one that's super cheap

take off all cushions 

these ones just unscrewed off

make sure before you buy it that you'll be able to figure out how to take them off

get it ready to be painted by putting garbage bags under it or some sort of protection so you don't spray the grass a pretty color:)

paint it with primer

spray paint is easiest and gives the best coverage

white is prime (heh heh) since it will brighten the actual color you will paint it - black will dull it down

make sure your eyes and mouth are covered so you don't breath in fumes or get it in your eyes

"you look like a movie star trying not to be recognized!"

that or a terrorist.

paint it with the color after the primer is done

2 coats is best

make sure you get the bottom of it as well

leave to dry

now for the cushions

i didn't get any pictures of making the top one. 
but it's going to be different for every chair and every cushion
i just copied what the original fabric was like
so i basically made a sack of sorts and sewed it on
make sure if your fabric has a design on it that you sew it the right way

most bottom cushions will be like this
cut a piece big enough to give 4 inches extra on each side
hot glue (or staple) one side on

pull the fabric super tight and glue on the opposite side
make sure your design stays on straight

do the same for the other 2 sides but LEAVE THE CORNERS
on the last side you do make sure it is pulled very tight

glue the extra fabric from the corners like this
making sure you don't have too many gathers and folds

cover up ugliness (this was on the cushion originally and i just ripped it off before i started

make sure you add a cute label saying you made it :)

put the cushions back on and you're done!
