Tip... make sure you remove the cap from the brush end also so that you can watch closely. When the brush end turns shiny... stop... you are full!
Thanks Colleen, for that tip! I read to be very careful not to overfill. Yet I had no idea how to tell. Since my blender pen was very dry, I went by how much is a typical fill, and stayed under that amount. I also did keep checking the brush end - and when it was feeling 'wet' I figured that was good. Your tip makes much better sense though. And much easier when dealing with the color inks!
Thanks for your great tip! Mary
