Using the instructions, you can make an 8.5 inch (excluding fringe) bookmark with heart motifs.

The BORDER and FRINGE is made in COLOR 2 as defined in the pattern.

About 12 yards of COLOR 1 and 8 yards of COLOR 2

I have used WHITE ROSE Soft Knitting Cotton Yarn.
Sourced from The Crochet Bella (online store)

Alternatively, you can use any yarn close to a yardage of 93 yards for 50g.

The pattern can be modified with repeat of the motif.
