My biggest female P.murinus is making her sac! She has a log hide that is up against the side of the glass. I taped some paper over it so the light wouldnt get in (so she wouldnt web on it). I lifted it up today and she has her bowl made! This is the same female that gave me my sac last year! Im pretty happy about this! I paired my smaller 4 inch female a couple of weeks after I paired this girl. The smaller one isnt showing anything to promising yet, but you never know. I just had to share
