This pattern takes its name from beautiful old diamond lattice windows on a house on Lambton Road in my neighbourhood. They have taken on different angles as the house has settled over the years, so they almost twinkle as the sun bounces off in different directions when you walk by.
The original sample was knit in Third Vault Yarns Companion 4ply, Cowtown gradient and Blue Steel colourways. A great commercial substitution would be Dream In Color Smooshy or Dream in Color Smooshy Kettle Hand Dyes.
Note: *It seems that knitters are not able to get the same number of rows out of their MC as I did. Keep in mind that everyone knits differently, and different styles of knitting will take up different amounts of yarn, even if gauges match. The pattern is written such that it does not matter where you end, but your bottom triangle will be smaller if you get fewer rows in. *
