If you're a paper nerd, like me, Hollo's pretty much rules.
They're a family owned local business. They have everything you would ever need for any paper project you would ever work on. When I got married 5 years ago, I made all of my wedding invitations (from scratch) with card stock and envelopes I bought here. You can even buy pre-made invites that you can print on. That's not what I did though because I am a lunatic.
If you like scrapbooking (I don't) well then they have all of that stuff here too.
Card stock in every color of the rainbow? Check. (It's really cheap. Last I checked it was $1 a pound.)
Handmade paper? Check.
Envelopes in every shape, size, and color? Check.
What does NOT rule? Their location. Brunswick. If there's any city in Northeast Ohio that I do not like to go to... yeah, Brunswick would be at the top of my list. It's definitely one of the Circles of Hell. I just can't figure out which yet. But I am still willing to drive there when I need paper.
