I saw these on Pinterest and thought I'd give them a try.
The pattern works for yarn, string and twine. It's a pretty easy project and quick to complete. Enjoy!
Note: This pattern can be worked either crocheting through the back loop of each single crochet or the entire stitch, I did both and each gives a different look.
Chain 4 and slip stitch into the first chain to form a ring.
Round 1: Make 8 single crochets (sc) into the ring, mark the first stitch of the next round with a removable marker.
Round 2: Make 2 sc into each stitch to end of round.
Round 3: *1 sc into next stitch, 2 sc into next stitch, repeat from * to end of round.
Round 4: *1 sc into next 2 stitches, 2 sc into next stitch, repeat from * to end of round.
Round 5: *1 sc into next 3 stitches, 2 sc into next stitch, repeat from * to end of round.
Continue to work in this pattern, each round adding one stitch between the increases until the bottom is desired size (mine are 3″ diameter). Move stitch marker to current position in work. For sides, continue 1 sc in each stitch without increasing until desired height (mine are about 1.5″ tall). To change colors, add new yarn where the round begins, cut old yarn end to about 3″ and then work over yarn end with new color for a few stitches. This avoids having to weave in loose ends later. At the end of the final round, cut the yarn and pull the tail through the last stitch. Remove marker, steam if desired.
