Have you seen DMC's Secret Perfume embroidery floss? I read about it here and I just can't get it out of my head.
This is the blurb.
The "Flower Bouquet” includes fresh fragrances such as Rose, Lavender, Lily of the Valley and Honeysuckle. The "Tutti-Frutti" includes tangy scents including lemon, orange, apple and strawberry. And the "Delicacies" includes delicious aromas such as vanilla, almond, caramel and chocolate.
It reminds me of scratch and sniff stickers that were all the rage when I was at school. We used to scratch those stickers to death. There was one particular brand, forgotten now which one, that was particularly good. I think in the end they were banned. Probably highly toxic.
Anyhoo, back to these threads. Does that mean that your embroidery will reek of chocolate, caramel etc?
