Here are a few occasions when the Wool Shade Book is invaluable: 1)You want to change a color in an Elizabeth Bradley design to make it fit in your room better, say making roses more salmony and less pink. 2)You work from charts in EB books or elsewhere. 3)You design your own work - brava! 4)You stitch the main part of the EB design as shown but change the background with some texture or pattern - which colors to use? I could go on! Unless you only work from kits exactly as designed and packaged, the Wool Shade Book comes in handy. Plus looking at the array of colors is cheering. It would be even more useful if the yarn samples in it were a smidge bigger, but they work fine as they are, and greed is bad. Recommended for anyone who does any stitching aside from kits. I already had an older version of the Wool Shade Book from when the range of colors was more limited; I use both and would not part with either.
