Took advantage of cold weather and a closed school to make these with dc. used whatever flowers/leaves/berries we could find in the garden and some left over glitter. Have hung them on our tree and they are very beautiful should last a few more days I should think. Handy tips: use boiled cooled water for a clearer ice and we just left them to freeze outside overnight. For the moulds we used the plastic trays and aluminium patty tins from some mincepies we'd just eaten
