I've probably said this before but I have a rather large crateful of felty scraps in my house - leftover snippets from various projects, some of which have worked and some of which haven't - and I don't like to see anything go to waste, so I decided to stitch some mini patchworks.
The idea of woolly postcards came from Christa Rolf's book "Stitched Postcards: Beautiful Textile Designs in Miniature Using Quilting and Mixed Media Techniques". I needle felted the felt scraps together (spent a lot of time fiddling around with compositions!) to make a patchwork mosaic just a few mm larger than an A6 postcard, then zig zag stitched them together onto some vilene underlay. And then I free machined lots of wiggly, squiggly patterns and doodles on top to cement everything together and level off the surface (because some of the scraps were denser than others). You then take a blank A6 postcard, attach the patchwork using double sided tape and zig zag stitch around the edges using a stitch width wide enough to trap the outer edges of the felt along with the edge of the postcard. Zig zag stitch around the perimeter about three times, shortening the length of the stitch each time around so that you end up with a really dense yet decorative border.
For that extra special touch Christa Rolf recommends adding some fancy stamps , so I went to my local Oxfam bookshop in Shaftesbury and invested in some classic collector's stamps.
Now, obviously you can't just pop these felt postcards straight into the postbox - I know, it seems a shame to put them in an envelope like a greeting card but at least you can be sure they will arrive safely!
