ELAN four-hole sew-through buttons provide a classic, balanced closure for garments, alterations, and repairs. This card includes 2 button sized 15mm (9/16 inch), and the four-hole layout lets you stitch in a cross or parallel pattern for a secure hold. Choose thread suited to the fabric weight and check spacing on a scrap so plackets sit flat and the buttoning action stays smooth through wear over time and after repeated use.
