wire mesh, about 2 rolls of the 24" stuff
wire, for putting her together
flour (for paper mache)
black spray paint
a bag of black spider web material
some type of glue
Step 1: Wire frame
take the wire mesh roll, unroll it and cut off about 3' so you have a 3' x 2' peice of wire mesh. fold it in half but don't make a crease so that you now have a piece that is 2' x 18" kind of teardrop shape if you are looking at a side profile.
the inside of the bend is her back side, take a marker and trace out a spider abdomen and head area then add about 3" to your line all the way around and cut it out on the top and bottom side of your mesh, the extra 3" are to connect the top and bottom.
bend the top 3" down and the bottom 3" up till they meet in the middle, use your wire to tie them together. hopefully you have a spider body, minus the legs
for the legs take the rest of the wire mesh roll and cut 4" strips the full 2' length, you will need 8 of these total
when they are all cut, bend about 1" of the long side all the way and do the same to the other side until the two sides meet, kind of a three sided tube like thing, and again use your wire to hold the two sides together.
after all 8 are done take one side of each leg and attach it to the body with your wire in a spider type fashion.
now you have a 3D flat spider looking wire body, if you now place your spider on a 5 gallon bucket you will be able to bend the legs to create joints,
duct tape all of your seams to keep them from poking through the next step. i used calking where the legs met the body to give a more uniform look
