Just sneaking in under the wire at Less is More with this one! The theme is yellow & green, I think I can safely say this qualifies. The stamp is by Papermania, stamped in Distress Ink in Pumice Stone then watercoloured with Cotman watercolours. The greeting is stamped in Hero Arts Butterbar Shadow Ink.
I’ve also just spotted that the current challenge over at Lisa B Designs is Spring Watercolours so I’m entering this card there, too.
