Looking for a quick handmade touch to add to your holiday gift giving? This t-shirt yarn granny square trivet is perfect! Quick to make, useful and even easily re-purposed as a tiny crocheted wall hanging (that is my real plan for this one, if I can find the time to pull it off.) Depending on the content of the t-shirt yarn you use, and the thickness of the yarn, a little beauty like this one can also be a pot holder. Add a little loop at the corner and maybe it is a decorative crocheted pot holder? And trivets are great for protecting furniture, or using as a giant coaster…
