Then it must be bought. If the book has great instructions for the technique it describes and most beautiful designs then it is no wonder that nevertheless of the 2 kilos of lace yarn one has waiting at home, a new skein has to be purchased and new project cast on.
I bought Nancy Bush's "Knitted Lace of Estonia" as soon as I saw it on the shelf in book store and cast on for this beauty:
(At this moment I'm at the second row of Lilies and cannot understand where a mistake is hiding, because the chart is faulty - I haven't been able to find an errata on the web so I laid aside the piece for awhile and finish something else I started )
This lacy beauty is knit with Harmony needles, which means I do not risk taking them on board. And since I would go nuts on a 12-hour flight and since Silvia gave me 3 amazingly soft skeins of new yarn from Grignasco I cast on on bamboo needles for Lily of the Valley Scarf from the same book:
There are lots of nupps in this scarf but I must say that I've gotten them right in my hand and it doesn't take any effort to do them. The scarf is 137 cm long.
Pattern: Lily of the Valley Scarf by Nancy Bush
Needles: 3,5 mm
Yarn: Grignasco Mousse (50% soya, 40% new wool, 10% silk; 185 mt for 50 gr)
I used just a tiny bit more that 2 skeins.
