Using some template plastic (or other similar transparent plastic), trace a square the size you need for your hexagons. I'm making one inch hexies, so my squares are 2.5".
Place one of your paper hexagons onto the center of the square and trace around it's outside edge.
Use your paper (not fabric) scissors to cut out your plastic square and then color around the outside edges of your hexagon with a permanent marker. Be sure to let it dry before you handle it and if you use a Sharpie, hold your breath. So stinky!
Use your new template to find the perfect fussy cut for your hexagons.
(Yep, I actually own that fabric.)
When you find the perfect placement, trace around the outside of your template...
and cut it out with scissors or your rotary cutting ruler and rotary cutter. Please don't use template plastic as an edge for a rotary cutter.
And, there you go. Perfect fussy cut hexagons!
It's helpful for finding the perfect spot on busy prints,
or aligning that polka dot directly in the center of your hexagon.
Yea! Happy fussy cut hexies!
ETA - I got that template plastic at JoAnn. It's less than $2 a sheet and is in the quilting notions area. I've also seen it at Hobby Lobby. I like the heavier weight more than the super thin stuff.
