This is a modular rose complete with calyx and leaves designed by Viviane Berty. Folding individual units is straightforward, but the assembly can be a little tricky, and unlike many modular models the folding continues after the assembly for both the Rose and the Calyx. For all the intricacies I think this is a lovely model and makes a great present. (Maybe think about making a few for the love of your life?)
For the Rose -
5 squares of solid coloured paper for the rose itself – both sides of the paper are visible in the finished model – however to ensure the model holds together a slightly thicker/rougher paper is preferred – Tant is ideal. Kami/Foil should be avoided as it is unlikely that the rose will hold together properly.
For the Calyx -
5 squares (same size as the rose) but the choice of paper is entirely up to you – I prefer to use the same type of paper throughout. The leaves are each folded from a single square – I typically fold two, which should be the same size and (ideally) the same type/colour of paper as the calyx.
In terms of size of paper 3 to 4 inch (7.5 to 10cm) is perfect.
For the Stem -
A wooden stick – as sold by garden centres to support small plants – these are often green and are only a few (3-4) millimetres in diameter. Alternatively you could use something like a barbeque skewer, but you may want to paint it green in advance. If you can slightly sharpen one end of the stick it will make the final assembly a little easier.
