For FP target I took 4 old seat cushions from outdoor patio furniture,the cloth ones and stuffed them in a box,perfect for FP's. not good for BH's.

if your going to use Styrofoam you 'll need to glue it or bind it tight.
if the stuff shifts it will be a buger to pull out them arrows. ya been there done that

If you have a Tractor Suppy Company near you,they use thick blocks of styrafoam to protect some of their equitment they get sent to them.
All you have to to is ask and they will give you as many as you want for free.Most of them are the same size..About 18" long,10"wide and 8"thick.
Your arrowswill pull out very easy also.They also last along time.I use them with target points and broadheads.
You can also use a cardboard box.Stuff as many plastic shopping bags in the box as you can.I hope this helps.

The blue or pink styrofoam works. Of course it's not like you have a Block on your hands or anything, but you can cut a blue styro sheet into squares, layer the squares up, and use duct tape to hold em together. They will chip some, but can take quite a few shots with a bow and arrow removal is a cinch.

I go shoot at a friends house all the time and other than his Glendale buck, we shoot the crap outta the homemade "Block".

It ends up being in a cube and you can kick them and then shoot at them...that way you have to judge the distance off the hoof and all that jazz...

Makes for a cheap fun afternoon of shooting (well, that and judo-points and tennis balls.)

a razor blade would cut the styrofoam nicely
