One Stop Button Shop — Sewing buttons as a | onestopbuttonshop.com
Two-hole, four-hole, shank and tack buttons compared by how they attach and the fabric each one suits.
Flat sew-on buttons are the default for shirting. Two-hole buttons lie flattest; the 4-hole pattern is the standard on dress-shirt fronts, where buttons run 11-15 mm across. Both attach with thread through the face.
On cloth thicker than shirting, a flat button needs help: sew it with a thread shank equal to the fabric thickness plus 1-2 mm. That stem of wound thread lets the overlap lie flat instead of puckering around the button.
On narrow screens, swipe or scroll the plate sideways.
Shank buttons carry their own loop on the back and are stocked from 8 to 20 mm. The built-in stand-off suits coats, blazers and heavy cardigans, where a sewn-through button would sit buried in the cloth.
Tack (nail) buttons are the workwear solution: a cap of about 17-20 mm is clinched through the cloth onto a stud. Jeans and workwear jackets use them instead of sew-on buttons because there is no thread to wear through.
Whichever type you sew, the lock is the same: wind the thread around the shank 3-5 times, push the needle through to the back and knot it. For sizes see the ligne chart; for holes and spacing see the placket guide; the homepage ties size, hole and attachment together.
