Do not try to cut through pins with the sewing scissors. It will not do the pins any good, and it will seriously nick the scissors.
Furthermore, don't iron fabric with pins still there. It'll melt the pinheads.
Make sure *every* pin is removed before you try on a freshly sewn-and-ironed top - use a magnet if you have to because you will have missed a pin, it will be HOT from the iron and it will STICK into the skin unde your arm when you try the top on, burning and piercing you at the same time!
I have a lovely scar and the bloodstain never fully came out of that top.
If "Grandma" sends a hand made outfit for the grandbaby - check it for sewn in pins. She also thought that my washing red & green fabric before cutting & sewing it was a silly superstition......
Pin in the sewn shut elastic casing for a two year old. Washed doll clothes with toddler clothes made from fabric she'd given me - left over from fabrics she'd just used to make a complete baby set (sheets, quilt, dust ruffle for under the crib, bumpers, etc. - back in the 1980s, so they still used bumpers in cribs). The print was set off by a lovely bright crayon RED.....which bled everywhere on that load of clothes.
I warned MIL to rinse & keep rinsing the first time she washed the quilt, dust ruffle, and bumpers because if the fabric sat for any length of time or got stuck in the dryer....it would be permanent.
I don't remember if that dust ruffle, quilt, and crib bumpers ever got used again......it's been 25 years or so.....I suppose I could ask. But I have a hunch that "no one would remember" or at least, no one would tell me......because she did start sharing that silly superstition about red and green quilt fabrics........
She really liked the feel of the crisp new fabric just off the bolt - washing it first made it feel "used" or something. She quit using the bright reds and greens most likely to bleed dye.....or rinsed a small piece out by hand & put it on a white paper towel to "check" for bleeding before getting a lot of patches hand sewn together after that!
