Found my beautiful old MM Stiffler in undeniable death curl on the 23rd.. measured to 6.2" even DLS and had one sac during his life (661 Spiderlings from Mitzy x Stiffler) and lived a full two years mature. He was my first tarantula. RIP buddy..
To preserve just cut the underside of the adbomen, remove the insides, fill with cotton wool then glue back togeather, you can insert metal wire through the legs for different poses or just let it harden in a natural position.
Not much too it to be honest
