I used Puffin Arts cardstock (some Dutch company) which is strong enough to make cards with so medium thickness, and messed around doing big circles with an embossing tool on the flower and radiating lines on the green leaf (yes the biggest light green circle is a leaf) over an upside down mouse mat. Probably not a kosher approach to embossing/ distressing - but it worked!
The button is out of my 'not sure if it's a replacement for clothes currently in my wardrobe' box, so I might regret using it at some stage. In fact I might go and check.... Anyway and some black linen thread that was already threaded through the needle I'd chosen in my needlecase. And the ribbons are a mix from the Crafty Ribbons bargain offcut pack, and other random ones that probably came off chocolate boxes...
It's 5"x7" and as ever no sentiment inside or anywhere else!
PS If anyone's having trouble with their ribbon stash DT Gloria has an amazing post on how she sorted hers out. I've followed it and now mine are all in one place, although I'm not brave enough to throw away ribbons under 1 foot long - unlike her!
