Well its a yes and a no; the original gun did have HUGE tags that made really nasty holes and I refused to use or stock them (I owned a quilt shop at the time); however the current generation has a much smaller needle and tiny tags which hold the layers better since we have moved to flatter wadding and don’t make holes in the fabric. I use them all the time and despite having several 000 in each box seem to be constantly running out!!!!
TIP: do invest in a tack remover as well as this will keep your quilt safe from little snips from your scissors and also stop you being tempted to use your best scissors to remove them (and spoil your scissors)
NB: all these products are in the shop
