I made this easy (and cheap - I only spent $1.50!) flag garland yesterday while watching an episode of Michael Wood's Story of England (a great program). I saw a similar project on the papernstitch blog, but I wanted to make a few changes to customize it for my space. In particular, I wanted the stickers to be white and shaped like little flags.
To make the garland you need some white string, scissors, and a package of rectangular white adhesive labels.
I cut three lengths of string to fit the area above my fireplace mantle. Each one is a slightly different length so they drape nicely when hung together.
Beginning in the center of the string, fold one of the label stickers in half with the string sandwiched inside. Work out from the center, placing a new sticker every 3 inches (7.5 cm). Repeat this on all of your garland strings.
Next, cut a small triangle out of the bottom of the sticker. This makes the flag shape.
Here is one garland...
And the finished project with three garlands!
This was such an easy DIY, I'm tempted to hang them everywhere : )
