I got this through the post today and started it imediately - I am finding it fun to do so far and fairly quickly you do start to see results.
I also find this relaxing.
The only downside is the packets the sequins and nails come in aren't re-sealable. once you've opened the packet you'll have sequins and nails everywhere unless you have something to put them in.
I solved the problem by putting the different coloured sequins in cake cases then putting the cake cases on top of each other and have put them in a little storage box and nails are stored in another storage box.
