Button-hole the edge of the split as you form the lattice. Insert your needle in the edge of the hole and make one button-hole stitch; then take your needle into the other side of the hole with another button-hole stitch. Then two button-hole stitches, and take your needle up to the top edge of the hole, near where you began.
This forms bars about 1/16-inch apart, and with two button-hole stitches in between.
This completed, turn the glove and do the same thing across from side to side, knotting the thread each time it crosses the under-threads. By this means, a tiny net-work is made.
This net-work is elastic, and will wear and wash into shape and last as long as the glove itself.
Making a Neat Patch.
Next to the fingers, the thumb is the worst problem.
I find that opening carriage doors has an unfortunate knack of splitting a glove, where the thumb joins the palm.
If there is plenty of room, this split I can be neatly joined up, but the better plan is to patch it with a tiny piece of an old glove.
Taking Care of Your Gloves.
Tack the patch in, and then with fine silk the colour of the glove, button-hole around the edge of the tear, taking up the under-skin as well. This keeps it firm and neat, and the patch may be cut away underneath, just leaving a small margin for stretch.
