My go to to start planning parties or showers are Pinterest, Etsy, and my Cricut Explore. I use Pinterest to start coming up with ideas. Then I use Etsy to see what products are available to make my vision come true. Sometimes I try to items myself using my Cricut Explore. Other times I make the purchase from Etsy.
I purchased my Cricut Explore One a few years ago when I was planning my wedding. I used it to create envelope liners for my Wedding invitations, I also used the writing feature of the Cricut Explore to address invitations.
