My piecing experience is a grand total of one BOM from 2017 and I've never done applique... but I'd love to join in if you'll have me! It'll be great to have the motivation to go back to the dark side to learn some new techniques and I loved the Secret Santa.
My room is blues and greys (bedspread is white with big grey swirls, curtains are pale blue, and existing cushion covers are Liberty Kussman in the blue colourway with grey backing) and I struggle a bit with things that have a lot of bold contrasting colours.
