I just remembered there was a thread a few weeks back about recycling - it kind of got a bit sidelined into general recycling rather than stuff for crafty projects but there were some posts with lots of ideas of things to reuse in card-making or other craft stuff. If anyone wants to check it out for more ideas, it's
here.
Glad you enjoyed the tomato paste tube! It's great for 3D projects too - I'm attaching a little candle tin I did a while back so you can see how it works for that kind of thing.
