Help....I'm re-lining a jacket that I've had for 15years. I bought a pattern for the lining pieces, so they do not exactly fit the jacket.

I tried to make up some width by cutting down on the seam allowances and consequently have come too close to the edges, some fraying is occurring.

The seam LOOKS okay on the right side, but I'm afraid when stressed the fabric is going to come apart.

Will the iron on webbing (ie: Stitch Witch, I think that is the name) help or what do you recommend to arrest the fraying and finish the seam?

My sewing machine is a super old wonderful Singer, but I have no zig zag stitch.

Hi Jackie,

As I can't see what your jacket and lining look like, it is difficult for me to say exactly what would work.

My first thought though, would be to cut strips of your left over lining. Open the side seams of your existing jacket lining and expand the width this way.

If you feel that there is too much pull or stress on that seam, no matter how you reinforce it, it will eventually come apart.

I know that what I'm suggesting is more work, but in the long run, it will be a better solution.

I have sent a photo to at least give example to what I mean. I hope it makes sense.

You may have to play around with the arm hole but this is really the best option in the long run.

The only other option I could give you, is sew a strip of twill tape or gros grain ribbon over the seam. Stitch down each side of the tape or ribbon and see if that helps.

I caution though, you may still have stress on the seam and end up having to take it apart and try the first suggested method after all.

I hope this advice is helpful to you Jackie. Please don't hesitate to contact me with any other concerns or questions.

Happy Sewing
