Dress makers pins and or stripped Cat5 cable, plus if you have one the waste from an office hole punch.My plan is to use 26 gauge copper wire along with green stuff and very thick printer paper from work to make a variety of pretty flowers for the base.
Maybe sun flowers since they're easier to scale with the base and mini.

Making flowers is fiddlly, and time consuming, but the thinner the paper the closer to "scale" it'll look. Tracing paper looks quite "in scale" but I've found it needs a "kiss" of Dullcoate to make the paint stick.
