All is full of love...

Some crochet cotton and PVA come together, based on this tutorial from Craft.

Be warned sticky crochet cotton is well, quite sticky.  I used a cocktail stick to move the thread around without getting into a big mess.

Tiny couching stitches hold it on to the card.  Perfect for a wedding acceptance rsvp card.  Maybe this will encourage me to make my Christmas cards this year?
