I hadn't tried just one colour in lots of shades on a page in ages, but I had noticed that they had a single colour challenge over on the crate paper blog (there is loads of inspiration and lots of different single colour pages scroll down and it is all on this page).
I went with yellow as this was one of the first sunny (yet cold as you can see from the picture) days this spring. I started using lots of mists for the background and experimented with crumpling up paper and then adding some stamping too. The papers are mostly from the new Maggie Holmes range which you can find here, though there is some Farmhouse chipboard and stickers in there too and a DIY shop ruler! I went from yellow to hints of gold with the sequins and polka dots on the tag which is from the DIY workshop ephemera pack (the ephemera packs are packed full of gorgeous embellishments).
Using a single colour theme works really well with mixing up using different manufacturer papers too - there is sill a rule I learnt from Shimelle that I apply when I do this. When you look at the base colour to the patterned papers decide whether it is cream or white, so you can use all your cream bases together and all your white bases together. So in my page I would say the base of the papers I have chosen is more white so I stuck to white cardstock and white based papers.
I hope you are enjoying the sunshine!
