Now as I am only just starting out I only have the few colours of wool that I have bought this past couple of weeks. That is pale green, dusky pink, purple, navy and some grey that I found at my mums from when I knitted a little cardigan for my son when he was a baby. This is why the little bits I keep sharing are all in the same colours.
I had a look back over the ideas on attic 24 and it appears you need a circle base of polystyrene that you cover in your base piece of crochet. Well for a start I have a feeling these specialised little bits and bobs will be overpriced and also surely there is something else that could be used?
Below is a picture of my covered base, grey is not very colourful I know but I'm sure when it is covered with flowers and whatever it will get better!
