A fabric school bag takes a lot of daily punishment, from being dropped on pavements to being crammed full of books and folders. A small hole often appears at a corner or along a seam first, and if it's left alone, the fraying edges tend to spread with every additional day of use. Catching it early makes the repair far simpler.
The bag is turned inside out where possible, so the patch can be worked from behind and stays hidden once the bag is used normally again. Any loose threads around the hole are trimmed away first, leaving a neat edge to work from.
Sew the patch firmly from the inside
A patch cut from a similar sturdy fabric is laid over the hole from the inside, overlapping the damaged area generously on every side. Small, close stitches worked right around the edge of the patch hold it firmly in place and resist pulling apart during everyday use.
Corners and stress points deserve an extra pass of stitching, since these are the spots most likely to give way again first if the repair is left too light. A double line of stitching here makes a real difference to how long the mend lasts.
Once finished, the bag is turned back the right way and given a gentle tug around the repaired area to check it holds under normal strain. Any part that still feels weak is best reinforced immediately, rather than waiting for it to open up again.
With the hole properly patched, the bag can keep being used through the rest of the school year without the damage spreading any further. This small repair takes very little time but saves the cost and hassle of replacing a bag that's otherwise still perfectly serviceable. A quick check of the other seams while the needle is out is always worth doing.
