Pinked seams, pinking, and pinks all have something in common. They have an attractive zigzag edge. Dressmakers use pinking shears to cut a zigzag edge on fabric to stop it from fraying. Mother Nature has created delicate flowers with the same zigzag edge to delight gardeners in spring.
What is a Pinked Seam?
A pinked seam is a seam that has been finished with pinking shears. The purpose of the pinked seam is to neaten up the seam allowance without having to sew or use a serger. A sharp pair of pinking shears is required to cut pinked seams. The shears, with their sharp zigzag edges, are ideal for cutting the pinked edges of the completed seams.
Why is the way you cut with pinking shears so important?
It is very important to cut the fabric on the straight grain when using pinking shears to create pinked seams. The reason is each little triangle cut into the fabric is actually cut on the cross or the bias. The blade and the zigzag rows of teeth that make up the shears are designed to cut cross cuts into the grain of the fabric. The cross cut triangles will not fray. This is why the shears must cut along the straight grain. Directing the shears along the straight grain sets the teeth at an angle and enables the teeth to cut into the bias. Cutting curved or diagonal edges is not advisable, because the pinked edges will fray.
Pinked Seams Techniques
You need sharp pinking shears for this process. This is a really important factor. Blunt pinking shears can end up making a mess of your seam allowance and the result is a frayed edge not a neatened seam allowance. That is exactly the kind of edge you are trying to prevent.
Step 1 - Sew the Seam
Sew your seam as per the normal ⅝” seam allowance. Press the seam closed to keep neat edges. There are two schools of thought on the pressing and cutting of the seam allowance. Press the seam closed and cut the two edges together on light to medium weight fabrics. Press the seam open and pink each side individually on medium to heavy weight fabrics.
Step 2 - Cutting Pinked Seams
Have your really sharp pinking shears ready to cut pinked seams. These are often hard and heavy to handle kind of cutting tool; notice they are actually called shears. Look at your shears, and you will notice the handles are different. This is to make the shears comfortable to hold and to give the maxim pressure to the cutting edge.
You can cut through both pieces of fabric on the seam allowance, or one edge at a time. The choice to cut through two pieces of fabric, or one, depends on the fabric. Always try out your process on a scrap of the same fabric because thicker fabrics may not cut cleanly if they are doubled.
Cut with the pinking shears close to the raw edge of the seam allowance. Take long slow cuts through the fabric pressing down on the table or cutting board with a firm controlled hand.
The cutting technique is important. Open the shears and fit the fabric into the shears so the edge of the fabric you plan to cut is right up at the top of the shears. Pinking shears have a long slow slicing action, not a short sharp snipping action. Practice this way of cutting to be sure you can handle the shears properly.
Step 3 - Pressing Pinked Seams
Open out the pinked seams and press firmly through the middle.
If you have decided to pink each side individually you will use your pinking shears twice to neaten both sides of the seam. If you decided to create pinked seams on double fabric then as you open out the seam both sides will already be neatly pinked. The finished seam will be ‘pinked’ on both sides of the seam allowance. This method saves time as you only pink once.
