In my free book "How To Host a Themed Party" I explain that the best thing you can do with a motif (design element or idea) is repeat, repeat, repeat! And that's what this party did really well, in a lovely, understated way.
Here's some ideas that you can borrow from the party - and remember, you don't have to have a butterfly party (although if you can't think of a theme, it's a goodie!), you simply have to replace your theme for hers;
Invitations - hand made and adorned with themed stickers.
Decorations - the birthday girl and her mom had made lots of butterflies out of coloured paper and pipe cleaners, and these were stuck amongst the streamers and balloons.
Craft - there was a craft table where the children could make their own butterflies, as well as sparkly masks.
Party Dress - made from butterfly fabric, with butterfly wings and headband as well - so cute!
Food - there was a giant butterfly shaped cake made colourful with a giant candycane body and lolly covered wings, "oh, I'm gonna love this cake, 'cause I loooove lollies" said one little guest. There was also plenty of garden-fresh treats and some butterfly cupcakes.
Games - as well as pass the parcel and plenty of running around there was a toy that blew tiny twists of paper into the air, and the children ran around with small nets trying to catch the 'butterflies'. There were also lots of bubble-wands left about for everyone to play with (and then take home).
Keepsake - the take-home gift was a handmade fabric bag (from themed fabric), with themed notebooks, rubbers, pens, and stickers inside.
It was the perfect example of how a simple idea can make a lovely party theme, and a little bit of planning and careful purchasing can pull it all together. A great idea, wonderfully executed. Get inspired, and at your next get together, no matter how big or small, put a little bit of themed-magic to the test!
