Clover Patchwork Pins (glass head) (line)
Clover's fine glass-head patchwork pins are sharp, slim enough to slide through quilting cotton without distorting it, and their glass heads survive a hot iron.
Not for: Sewists who mainly work with knits, which need ballpoint pins, or with very fine silks and sheers, which need extra-fine silk pins.

Clover Flower Head Pins (line)
Flat, easy-to-grip heads and long shafts make these versatile pins convenient for quilting, pattern placement, and everyday sewing.
Not for: Ironing directly over plastic heads or pinning very delicate fabrics.
Which one fits you
quilting through thick layers
Dritz Quilting Pins (line)
Their extra length holds batting and backing together without the pins working loose.
Not for: Garment sewists pinning single layers, for whom long pins get in the way.
knits and jersey
Dritz Ballpoint Pins (line)
A rounded tip pushes knit fibers aside instead of piercing them and causing runs.
Not for: Woven fabrics, where a sharp point pins more precisely.
flat pinning for appliqué and pattern work
Clover Flower Head Pins (line)
The flat heads lie flush, so a ruler or iron can sit on top of the pinned layers.
Not for: Anyone who wants pins that are easy to grab quickly from a cushion.

Brands that matter

- Karen Kay Buckley: Well-regarded long, thin pins aimed at quilters and appliqué.
- Prym: European notions brand with dependable glass-head and fine pins.
What to avoid
- Plastic ball-head pins if you press with pins in place.
- Unbranded bulk pins with burred or blunt tips, which drag and snag fabric.
- Thick dressmaker pins on silk, chiffon or fine cotton.
- Bent pins: replace them, because they shift fabric and can strike the machine needle.
Questions
Can I sew over pins?
It is risky. The needle can hit a pin and break or knock the timing off. Remove pins just before they reach the presser foot.
