Taxidermy habitat question

[Mudranger1]

Can anyone help me out on making like a prairie grass base for this. Instructions? or for a semi affordable price build one. I want to kind of mimic the grass he was in and cover up the bolts and maybe the back of the mount

This likely won’t help much but thought I’d post any way. This is Morgan the mule deer, he’s a captain.
Jack looks great!
