Good morning ladies, I need help from the well-informed women on here. I sell jewelry and my packaging is in a kraft cardstock pillow box. I cut them using a Sizzix die with my Big Shot. What would be the best pound cardstock to use? I'm currently using a thin one purchased from Hobby Lobby and it's too thin for my liking. BUT if I go too thick, then I'm afraid that the scored edges will break open, tear, or have those ugly frayed edges. Can anyone point me in the right direction? Brand suggestions, poundage, etc...I appreciate all if your comments!
