My current "quilt" project is Fernhill (a gorgeous quilt pattern by Lynette Anderson Designs) and Lynette used Weeks Dye Works threads for the hand embroidery on her original quilt. There is a conversion for DMC colours on the pattern, but I wanted to try these hand over dyed threads for myself. I managed to find a UK supplier, Peakside Needleworks, and ordered the colours that Lynette suggested. These threads have unusual names, such as Indian Summer and Schneckley, Molasses and Caper. The variegation on these threads is very subtle, and they really are lovely to sew with. The only problem is the cost, as there is just 4.5m on a skein (DMC has 8m per skein) and they're almost 3x as expensive as DMC (depending on where you buy your threads from) so I'll have to save these ones for very special projects!
