@saab,
I'll have to look up proper flower frog usage (we used to have a floral designer, Tico, here at a2k, miss her). I think that it works well with thick stemmed plants, to keep them in the order you hope to maintain in a vase. I've either done devil-may-care gatherings of flowers/leaves, branches, or sort of dramatic very big bouquets (learned from my old gallery/studio business partner who was extremely good at that), but in neither case using flower frogs. I should show some of her big bouquets, just terrific. Especially the cat-0-nine tails.
My car hasn't been in the garage here, poor thing, but it only has snowed a wee bit in the few years I've been here. But Sweden!!!! I picture it snowing a lot.
Heh, I bet you have a Saab. My friend Krista has only had Saabs for years - she was born in Estonia, spent time in Sweden before arriving in the US in her teens. I met her in my first class at the university we both ended up in.
Meantime I have a good sturdy old Volvo.
