Nesting Seams

Nesting seams (also called butting seams) is a technique that creates perfectly matched intersections without pinning. When two rows are joined, opposing seams are pressed in opposite directions so they 'nest' together — the seam allowance of one row faces left while the adjacent row's faces right. When the rows are placed right sides together, the seam allowances lock against each other, keeping the intersection perfectly aligned as it passes under the needle. Nesting seams is essential for achieving crisp points in blocks like Nine Patch and Ohio Star.
