Bohin 玻璃頭珠針 3/16 彩虹色

I love that I can iron right over these pins without worrying about the heads melting. The rainbow glass colors make it easy to grab the right one in a hurry.

The rainbow assortment is perfect for sorting my sewing projects by color, and the glass heads stayed put even under a hot iron when I tested one on a stubborn seam. The pins are slim enough for fine fabrics but hold layers securely, and the box keeps everything tidy on my desk.

I was a bit skeptical about ironing over pins, but these glass heads didn't melt or warp at all during my quilting project. The rainbow colors make them easy to spot on my cutting mat, and the 3/16-inch size holds layers together without slipping.
