Pineapples that point inward, ten in a circle. Outer border has 20 sideways pineapples in a band.

The pattern is two charts, one for the border which is worked in a single piece and grafted to itself to form a circle. The second chart covers the main body of the doily. As the pictures are not perfectly clear, there may be some confusion as to the number of chain stitches worked, as well as differences between double crochet, trelble, and double-treble. There are some written numbers to provide clarity for these issues.

There are virtually no written instructions, only charts.
