Are you trying to think of a personalised gift for some one special? Why don’t you make a personalised bunting?
The basic materials that you need are :- a string/ ribbon of some kind to hang it on ; Card to decorate (which you fold over the string and shape into a triangle or square shape,) and glue to seal it shut.
You could write Happy Birthday and their name ….on each flag, or whatever the occasion is. You could Choose different coloured card for each flag. How about trying your sewing skills and make it out of material?
Have fun crafting.
