I consider myself a tight crocheter, but I did have to go down two hook sizes to match the designer's gauge on this Circle Hot Pad by Esther Thompson. As she said, gauge isn't very important for this potholder/trivet, but you do want to have a nice firm fabric to protect surfaces or your hands from the heat. This was very quick to make and is so cute and totally giftable. The Hobby Lobby Crafter's Secret Cotton in the Desert Gold colorway looks modern and chic. There is a free version of this pattern on the designer's website.
I added a hanging loop by chaining 10 at the end of the last round, slip stitching the chain to the trivet next to where I started chaining, then turning and working 20 SC's back over the chain. A 1-inch wooden or metal ring sewn to the trivet would also look nice as a hanging loop.
There was also just enough of the main color (Desert Gold) left to make a coordinating 4-inch-diameter coaster in 6 rounds. I made it double-layered like the trivet, but for the coaster I slip stitched it together with the ivory yarn for a bit of contrast on the colorful side.
The multicolored balls of this Crafter's Secret cotton are 57 grams, whereas the solid color balls are 71 grams. So, using the solid color as the contrast color for this project, you have enough of the solid color to make two trivets (if you don't use any to make a coaster, the way I did).
I gifted the colorful trivet set to my niece Renee, and I made another set to give to my sister Juanita in the Hobby Lobby Crafter's Secret Cotton in the more neutral-looking colorway called The City.
