Hope you don’t mind another post from Christmas past, but I still get questions about them from MSE and newbies here.
The punches I use are from Stampin’ Up (the plain one measures 1 3/8ins), however there are a lot of other nesting punches out there, including these (below), but I can’t advise you on which ones you need as I haven’t got any actual experience of them.
This year I’ve used these flat stickers (Hobbycraft 99p) I’d have preferred something with a bit more definition but so far I haven’t found any “new” puffy, 3D stickers … but I am still looking.
…. and sometimes I use a little bit of sellotape on the foil to stop it ripping, if I make a mistake an have to reposition the mint etc. I use double sided tape to stick everything together. Then I pop four mints in alternating colours in a pretzel bag and tie with a ribbon.
The pretzel bags measure 2ins x 9ins and I always get them from this e-bay seller.
