I found a kit in a charity shop so had a go using some old spare glasses

start by dissolving a little gel in a saucepan then soaking the wick, cut to an inch or so longer than the depth of your chosen glass,  in the gel then let it dry on some paper towel

fix one end of the wick to the base of the glass with a little blu tak or plasticine, have to hand a skewer or matchstick long enough to balance across the centre of the glass later

dissolve more gel in the same pan, you can reheat the excess from the priming exercise if it has set by now

carefully pour a little dissolved gel into the glass and swish it around to coat the sides then sprinkle in glitter or sequins of your choice. You can see here my sprinkling was a bit heavy handed

holding the wick upright with one hand pour in some more gel then a little more glitter and repeat until the glass is nearly full. I used too much glitter on the topping up stage which gave a layer effect I hadn’t intended

now balance the skewer across the rim of the glass and drape the excess wick over it while the gel sets

once set trim the wick

tip: wash the pan by hand to avoid coating other stuff in the dishwasher with gel
