Day 3's Challenge was String Art.
I don't actually own a sewing machine and I don't sew if I can help it, but I bought an embroidery template once upon a time and I have plenty of embroidery thread from my occasional flings with Cross-stitch... The template is meant to be for a fairly elaborate border, but my injured hand isn't up to much by way of sewing, so I traced out just one part of the image with my hole-poker. Then I stitched it, and finished the card in the standard way. The other interesting feature of this card is a genuine antique button - I inherited a box of antique/vintage buttons from somebody's grandmother, and this one was saved for something special.
Day 4 is a White Space sketch challenge - all the decorated parts of the card have to fall into the coloured part of the sketch, with the rest of the card plain cardstock.
