Luckily, this next step is a pretty easy one – definitely not one that requires perfect stitching.

Securing the Seam Allowances

18th century stay construction is unusual to a modern sewist because you bone each panel, sew the seam allowances down, and THEN sew the panels together, rather than sewing the panels together and then pressing down the seam allowances.

The advantage of the 18th century method is that it makes it easier to adjust the stays later – particularly if the adjustment you need is inserting a panel.

Because the stitches just need to hold the seam allowances in place, they don’t require a lot of strength, and can be quite large and rough.

While your stitches themselves can be rough, there are a few things that will give you a better result at this step:

• Make sure you have basted around your pattern piece exactly on the line you want to press your seam allowances back on, so you press the same amount of seam allowance back on each piece mirrored.
• Press your seam allowances back with an iron so they are nice and flat
  
• Sew back the seam allowances for both the left and right panel, and then check them against each other to make sure they are perfectly symmetrical.   This is particularly important at the front point: I press and sew both points at the same time, continuously checking to make sure the points end up even.
• Sew the seam allowances down all the way into the tabs – if there is a slight curve, distribute the ease of the seam allowance and then use the iron to press it flat:

And that’s it!

And then you’ll have assembled stays!

(and then you have the tricky parts, like seam tapes and binding…)
