When sewing seams...
...the fabric is usually oriented with its 'right sides' together.
With French seams, however...
...they are first sewn with the 'wrong sides' together...
...and the seam is then trimmed...
...leaving a very small seam allowance...
...before the project is turned inside-out.
The same seams are then re-sewn...
...with the raw edges tucked inside!
The resulting seams are quite neat and 'fray-proof'!
Next time: the finished pillowcases...
...all fifteen of them!! :)
