Pattern not centered to shape
I've been struggling with this for a while looking through tons of videos and such but nothing seems to talk about centering the pattern so it won't be cut off.
In the screenshot, to the left is my pattern Artboard is 4.25 Square I dragged this to my swatch panel already. For the larger artboard, I have a shape that is sized 8.5 x 5 I would like the pattern tool to center the pattern to my object.
Why does it not center it? I am creating designs for Tumblers and would like my patterns to be seamless. Need patterns to match or connect edge to edge.
