We had a bit of help with this one - thanks to Roath Park rangers who organise this event as a fundraiser every year.  Eilir and I went along to Roath Park and had the choice of creating either our own wreath, yule log, or table decoration.  I wanted a log, Eilir wanted a table decoration (I think he fancied the look of the oasis), so we ended up with one of each.  Despite starting on separate projects, it very quickly turned into one shared project.  We collected bits of fern, fir, holly, pine cones etc and started to randomly arrange them around a candle by pushing the bits of plants into the flower arranging oasis.  Eilir was soon finished with this task and wanted me to finish it, as my yule log making (which required attaching the different foliage with metal staples and a hammer) looked much more fun.  I'd try to start it off, getting the staple in place, then Eilir would hammer it fully in.  He soon became expert, complaining if I hadn't set it up properly "You've hammered into the plant, not the wood - I can tell".  His enthusiastic hammering produced some squished holly berries and a lot of smiles.
