I sometimes think I do too much blog hopping and dropping into the forum but the ideas I've found this weekend are fab. Here's a picture of the little beauty I found when browsing. If you would like the dimesions and folding/cutting lines, take a peek http://sheetload.blogspot.com/search?updated-max=2008-12-15T21%3A25%3A00-06%3A00
It's very easy and only took about 15 minutes to put together. Obviously you can decorate as much as you like, or as little. But it is quite cute and dinky in size, made to take about 5 notecards and envelopes. Would make a lovely gift!
