This simple round coaster is made from a flat crocheted circle with a neat, finished edge. It’s a quick, beginner-friendly project that works up in one sitting.
What You Need

- Worsted weight cotton yarn (cotton helps the coaster lie flat and absorb condensation)
- Crochet hook (Suggested: 4–5 mm, matched to your yarn)
- Yarn needle (for weaving in ends)
- Scissors
- Stitch marker
How to Make It

Step 1: Start the Center
Start with a magic ring and work a small number of single or half double crochet stitches into it (Suggested: about 6–8 stitches), then pull the ring closed and join with a slip stitch to complete the first round.
Step 2: Increase to Keep the Circle Flat
Work a second round, placing two stitches into certain stitches from the first round, spaced evenly around, so the circle grows wider without curling into a cup shape. Continue working rounds this way, increasing by the same number of stitches in each new round, checking often that the piece lies flat rather than cupping or rippling.
Step 3: Reach Your Desired Size
Keep working rounds with evenly spaced increases until the coaster reaches your desired size (Suggested: about the width of a standard drink glass or mug, checked by placing a cup on top as you work). If the edge starts to ruffle, you’re increasing too much; if it starts to cup inward, you’re increasing too little.
Step 4: Add a Border (Optional)
For a neater finished edge, work one final round of single crochet all the way around without increasing, or try a simple scalloped edge by skipping a stitch and working several stitches into the next one, repeating evenly around the coaster.
Finishing
- Fasten off and weave in both loose ends securely with the yarn needle, one at the center and one at the outer edge.
- Lightly press or steam the coaster flat if it looks slightly curled, following the care instructions for your yarn.
- Make a second matching coaster by repeating the same steps, if you’d like a set.
Helpful Tips
- Use cotton yarn instead of acrylic, since cotton holds its shape better and won’t stretch out from holding a cold or warm drink.
- Count your stitches at the end of every round to catch any missed or extra increases before they affect how flat the coaster lies.
- Place a cup or glass on the coaster periodically while working to check that the size and flatness are turning out the way you want.
