Cautionary tale about hemming a dress tartan

[Dixiecat]

Putting the interfacing into the hem would have worked pretty good without leaving a ridge at all.

I've hemmed a kilt in this tartan so I know first hand how thin this is. You can see the kilt posted in the Heraldry and Tartans forum.

Actually, what I'd really do is use a strip of thin non-fusible interfacing that was 1/2" wider than the hem. I would then pink one edge using my rotary cutter with the pinking blade. Lay the strip inside the hem so that the non-pinked edge was against the fold. With the hem folded up, the interfacing would be sticking out of the hem by 1/2". Then I'd sew the hem as usual through the interfacing, ignoring the interfacing as it were. When you press the hem, you'll not see a ridge at all as the hem and the interfacing are graduated. The pinked edge of the interfacing would not leave a ridge.

There's some very thin interfacing available on the market these days. Just make sure it's a non-fusible!
