An oval rug is crocheted in the round, but the centre must be elongated in order to achieve the oval shape. This is achieved by starting the rug with a long chain and working on both sides of the chain in continuous rounds. Single crochet or double crochet stitches can be used to create this style of rug. Cotton yarn is a popular choice for crocheting rugs, because it is absorbent and washable, but any washable yarn is suitable for the project.
Crochet a chain that will be the centre of your oval rug. The rest of the rug is worked around this centre line. See Resources if you need to brush up on your chain stitch, single crochet stitch or slip stitch, which are used for this project.
Single crochet three times in the second chain from the hook, then single crochet once in each chain across to the last chain stitch.
Make three single crochet in the last chain, but do not turn.
Continue working around the opposite side of the starting chain, and single crochet in each chain back to the starting chain.
Do not join rounds. Place a stitch marker or hair clip on the first stitch to mark the start of the round.
Make two single crochet in each of the next three stitches to increase around the curved edge of the rug. Then crochet down the length of the rug to the opposite end and make two single crochet in each of the three stitches in the end. Crochet back up the opposite side to complete the round.
Continue in the pattern outlined in step 6, increasing three stitches evenly spaced in the ends of the rug. You evenly space them by skipping one more stitch between the increases than the round before. For example, in the next round, you'll skip one stitch between each increase, then you'll skip two stitches between each increase in the round after that, and skip three in the next round.
Join with a slip stitch in the first stitch when the rug is the size you want, and you are ready to fasten off. Chain one and cut the yarn, leaving a six inch tail for weaving in with the yarn needle.
For a thicker rug, use two strands of worsted weight yarn or a super bulky weight yarn and a larger crochet hook, between size K and size P, to crochet the stitches.
Yarn can be slippery, so you may want to invest in a non-slip rug pad to place under the rug to stop it from moving, or purchase a non-skid rubber rug backing compound that you apply to the back of the crocheted rug with a paint brush.
