I was in Florida recently and found (in the big Walmart store in Kissimee ) a brilliant range of rhinestone nail art stickers - most of them priced about £1.50 per pack of 10 or more. With them being a bit different from the usual here, I brought loads back (they're tiny packs and fit into even the fullest suitcase !). One design was a tiny heart made of red stones, + other variations in descending sizes. Not everyone wants all 10 nails deorated, but even one or two look really pretty. So I'll be plugging them for Valentine's Day. I sent my daughter to school with them on - so she'll no doubt show off - and drum up a bit of trade for me to boot!
Most folk who go to the states can find a Walmart easily. Ask all your friends & customers to bring back some packs for you. (The saving on a caseload would cover the airfare and then you could argue with the tax man that it's only a trip to the suppliers' !!!!!!)
Other packs included pink rhinestone butterflies (£1.50 for 15), rhinestone daisies, palm trees etc.
Hope this helps.
