Joining two pieces into ONE!

Introduction to the method of joining corset pattern pieces

Same way we can split one pattern piece into 2 of them, we can joining 2 pattern pieces into 1.

We might want to do this as a preparation step for other pattern manipulation methods such as adding gores or gussets to the pattern.

It can also come in very handy when working with fabric pattern matching.

No matter the reason, you’ll know how to do it with this tutorial!

Pattern used as an example is Underbust Corset Pattern NORA by AraneaBlack.

Preparing the pattern pieces for joining

Pick 2 neighboring pattern pieces to join.

Find and mark their circumference lines if they don’t have them marked already.

Draw a horizontal line that will be used as the new waist line later on.

Positioning the two pattern pieces for joining

Start by laying the pattern pieces on to the new waist line.

Make sure to match the original waist lines with the new line.

Pattern pieces should touch each other , “shoulder to shoulder”, on their waist line.

The rest of the pattern circumferences should overlap.

Tape them together.

Measuring lost space on overlapping

Draw a horizontal line on a right angle to the waist line, right through the point where the pattern pieces touch.

Measure the widths of the overlaps, on both sides from the newly drawn horizontal line.

Marked as “a”, “b”, “c” and “d”.

This is the amount we lost due to joining the pieces together.

Extending and adding circumference lines on to the corset pattern pieces

Extend the other circumference lines outwards.

Draw a new line that is parallel to the waist line so it sits right on the tip of the overlapping pattern pieces.

There is no need to do this if the overlap starts from the waist line.

Adding the lost width due to overlapping on to the sides

On the circumference lines, measure out the values of “a”, “b”, “c” and “d” on the opposite sides on which they where measured.

We will use the original seam lines to draw out the new seam lines as we want to try our best to keep the overall curviness of the original pattern pieces.

Drawing the new seam lines on the joined corset pattern piece

Use the original pattern pieces are “rulers” to draw seam lines of the new pattern piece.

Match up the old pattern piece on to the point where the overlap starts.

Anchor the piece with a pen or pin and pivot the pattern piece until it touches the marked point.

Copy the seam line.

Repeat on all sides.

Smoothing the new seam lines of the joined pattern piece as well as making new edge lines

Smooth out the new side seam lines and draw the new shape of edges.

Remeasure all circumference lines to check if they stayed the same.

Mark the new grain line.

Walk seams and make any and all necessary changes.

Ending of the tutorial on how to join two corset pattern pieces into oneo

Your new pattern piece is ready for other pattern modifications and adjustments.

Always make a mockup to test and fine tune your pattern before cutting your fancy fabric.

Happy sewing!!!
