Your challenge for today is to mend an article of clothing you would have otherwise thrown out. Here’s a video tutorial that shows two different ways to mend a small t-shirt tear. This technique can be applied to similar cotton or cotton blend fabrics as well. (Be careful using a hot iron on fabrics made mostly of synthetics.)
Also, here’s a post with several tutorials for different types of stitches.
If you don’t own the supplies to mend, use this opportunity to gather them. It doesn’t cost a lot to assemble a basic sewing kit. (Add various small spools of different colors of thread to this). And then you will have it for the next time something inevitably, but not irreparably, rips.
