Olaf Beadwork Pattern Books use Japanese size 9 glass seed beads. When this book was published Olaf packed their size 9 seed beads in 5 gram packets, here at Polly’s Beads our Japanese size 9 glass seed beads are packed in 10 gram packets. This is important to remember to not over purchase your quantities of beads. Olaf suggests size 10 crewel needle , our experience over the past 10 years is that the eye of a size 10 crewel will not go all of the size 9 seed beads so we have been recommending size 13 beading needle. In this book there is a pattern for all the pictures that appear on the cover.
