I thought you might appreciate a mini-update on my sisters of battle project :) I was initially struggling with the bolter as all the space marine versions are far too big! Getting a thin, sleek bolter was proving to be a nightmare. Then I was advised to try the forgeworld Umbra patter bolters, which I did! They're perfect!
They're still big and beefy, like a bolter should be, but without overwhelming the model. Now I just need to find some suitable flamers and melta guns!
