My team is doing a fun fold challenge this month so I'm trying out several. I saw a couple of versions of this Pinwheel card on Pinterest and decided to give it a whirl (get it?)
If you want the instructions, there are several out there, just go to YouTubeTM and use their search bar.
Tip: Go with a non-directional double sided card stock. This is not a SU DSP, just something I picked up from a big box store because I didn't want to mess up my SU DSP in case the card didn't come out right.
The finished card dimensions are 4 1/4" by 4 1/4" so it will fit in a standard A2 envelop. The inside dimension is 4 1/8" by 4 1/8"...gotta make room for those creases.
