Hayley Quince - What a breath of fresh air!

What a great idea! You pick things that the person likes and this company makes an illustrated card including all the things you chose. I added his love of fishing, the dog, and his awful jokes - the card was perfect. Brilliant idea. Card arrived, lovely quality.

Sue Blair - Ordering for her dad's 60th

I am absolutely thrilled to pieces with the valentines card I bought on this website, it is just too brilliant to put into words! I included our cat and his obsession with Formula 1. Where other card websites failed, Silly Robot Cards absolutely have come up trumps!

Sarah Salt - Valentine's card for her husband

Finally a card that actually gets her! Mum loves her tabby cat, Strictly Come Dancing, and a glass of red wine - and now she has a card with all three. The kids couldn't believe it. She's keeping it forever.
