You will need:
- crochet hook
This project is worked in single crochet. For the finished product, I've hooked into one side of each stitch, which gives it a neat "ribbed" texture (I tried to illustrate the difference in textures in the 3rd and 4th pictures, below).
Step 1: Start Your Chain
Step 2: Start Hookin'
NOTE: to get the "ribbed" texture in the picture, hook in to ONE side of each loop; the side furthest from you. Do this before AND after you "turn" your work.
Step 3: Embellish the Edge
At this point, make sure your working yarn is on the same edge as the tail from the beginning of your work (you'll need this for step 4). If it isn't, you can add another row, or rip one out.
You are going to have wide, loose spaces between each "rib", along the long edge of your fabric (I circled these in the second picture below). Crochet along the long edge, single-crocheting into the tight spaces, and double crocheting four times in each loose space.
Step 4: Seam the Edges
Step 5: Finito
Also good for other temperature-sensitive beverages.
