Here's one of the greatest secrets of good sewing.
The iron is your best friend!!! Seriously, when it comes to any
kind of sewing project, ironing the death out of everything (especially
finished seams) will make the difference between a shoddy piece
of boy-sewing and the smooth professional work of the manly man
who knows what he's doing! Grrrr.
For the breeches repair, we settle the tailor
ham (in this case, a rolled dish cloth) into the tube of the leg
and mist with water.
With the iron on the proper setting (linen, in
this case), we press the area of the hole, flattening out any wrinkles
and frayed edges.
After the area has been ironed, cut away all the
ugly fraying so that you have a nice clean-edged hole. Be careful,
but don't be too worried about making the hole bigger. You would
rather have a large clean patch, than too much fraying to tuck under.
Once you've done all this, iron it again!
