I absolutely love succulents, especially when they're used in unique and unexpected ways. Succulents Galore has a beautiful selection and you can buy them in small or large quantities. I think they would be lovely centerpieces and also make great wedding favors.

Brydferth makes beautiful accessories adorned with handmade, intricate rosettes. There is plenty to choose from - headbands, necklaces, broaches, bracelets - in a wide variety of colors. You can see the ones above, and more, here. I think the headbands would make a great bridal accessory, just a little pop of color!

Polka dots can be tricky, but if done right they can be really timeless and cute. I love them when used with neutrals, and black and ivory. Clockwise from top left: Modcloth, $20; ASOS, $30; J.Crew, $59; Forever 21, $27. Center: Cecil & Co, $22.

These homemade marshmallows from Brooklyn's Whimsy & Spice are just perfect and so delicious. With flavors like chocolate, maple, rose vanilla, and cardamom, they're hard to resist. I think they would make great gifts and wedding favors too. You can buy them here and also see the rest of their goodies at their online shop.

I really love vintage frames and chalkboards so when I found them combined at the Revived Vintage shop I was thrilled! I think these are so beautiful and a great way to dress up a chalkboard or make use of a frame in a unique way. You can find the ones pictured above here and here.
