This is a pattern for a small, round crochet doily made with a small amount of 100% mercerized cotton yarn, category 2 and a hook size D (3.25 mm).
Another option would be mercerized cotton thread size 3. You can even use size 10 thread (with a matching size hook), but the finished doily will be significantly smaller.

Specific yarn that I used for the doily shown in the photos is YarnArt Begonia.

The finished doily measures about 7 inches in diameter.

The skill level is advanced beginner. There is also a very detailed video tutorial (the link is included in the pattern).

The pattern is written in English using the US crochet terminology (no symbol chart available). Video tutorial is available.

This pattern cannot be redistributed. However, you have the permission to sell finished items made from this pattern.

This is an instant PDF download, and the sale of the pattern is final. If you have any questions about the pattern, you can always contact me, I’d be happy to help!
