Prickly labels!

Bane of my life too. They are usually made of tough nylon as you say, with razor sharp edges and sewn in with invisible barbed wire. Grrr. If we are meant to remove them, could they not at least be sewn in with a different colour of thread. I have been known to finish up with a hole in the back of the neck of a fragile garment, and I am very careful.
Labels in the side seams of camisoles too, dig into my sensitive bits! Sometimes I feel I am reliving the "Princess and the Pea!"

I have had similar problems. I was going to pick up some friends on our way to get a coach. Only when I was in my car did I realised the new bra had several very prickly lables. I got her to stick some scissors in her bag and once we parked up to go to the coach she performed a lable removal operation in the carpark.
I also had my back badly scratched by the waist band of a pair of walking trousers which folded over and rucked up. That was so sore that next day I had to put a big dressing over the skin.

I have problems with my sight so I have an awful time trying to find the correct place to snip.

Some of them bring me out in hives.

I leave a few threads visible as some sweaters I find it difficult to tell back from front with polo necks.

same here, when I buy something the first thing I do is to cut the ruddy things out, and they are so huge sometimes too.Grrrrrr.

GS's ... they are not horses!

In a pair of trousers I bought recently, there was a label so stiff that it scratched my hip. I cut it out, but why do manufacturers make them out of such stiff materials. My DD has an awful time removing every label in my GG's clothing, as they all have sensory processing disorders, and can't stand anything that irritates their skin.

I hate the bloody things. And it just doesn't make sense to buy a cashmere top or similar and have a label that shreds your skin. And when you cut them out, it's not really a good look, either! Not to mention my husband who ruins his shirts by cutting off the label without his specs on, and makes holes in the shirt!
