I am using an incredibly soft yarn from Colourmart, 1/15 NM, three strands twisted together - it’s a dream to work with.
I used the Dorset Button tutorial from BurdaStyle to make matching buttons. This was one of the reasons this sweater took so long to complete - when I realized I could not find any buttons that worked, I lost interest.
I made up my own knitting chart to help me get the hang of the lace pattern. Reading directions as prose always give me problems - I am forever losing my place - and this really helped.
