I've been perusing a few websites with many wonderful images and these are my favourites so far:
1. Style Me Pretty
2. 100 Layer Cake
3. The Inspired Bride
4. Marry You Me
5. Once Wed (Balqies' recommendation)
All of the above are wedding inspired. Here are some design blogs with ideas that can be applied to weddings, combined with your individual flair *wink*:
1. Twig and Thistle
2. HELLOmynameisheather
3. Sweet Tooth (cakes and desserts galore!)
4. Somewhere Splendid
I'm planning on using some of these ideas for an upcoming personal event (nothing wedding related!) which could possibly include some simple decorations, delicious homemade desserts and lots of fun. Watch this space!
