I found these photographs today & have realised I never uploaded them - from 2013's Christmas. Some Paper Bunting Christmas cards I made all that time ago. Quite a lot of work, but they do look good at the end of it all.
White A5 card folded in half with a Christmas print taped onto the front half. THe first ones I did like the photo below - the Christmas paper covering the whole front of the card with about a 1-2cm overhang onto the back over the folded edge - looks a bit more finished). I think the cards looked better though leaving a small border of white card showing all the way around (see below).
Then cut out an assortment of small 'bunting' triangles from coordinating Christmas printed papers, thread a needle with gold thread, tie a knot in one end ...
... and sew them all together, leaving gaps between each one to string them out across the card, allowing a bit of slack so it looks a bit more like they might be hanging up.
Tie off the other end of the thread too and then use double sided tape to stick the triangles at each end down (and in doing so hide the knots).
Stamp out some sort of Christmassy word (like 'Christmas' for instance!!)...
Add a little something to the back of the card for fun - here a small punched out tree and a left over triangle. All Done.
