Felt: I use only 100% wool felt, as it’s beautiful to work with and kind to the environment. It creates a quality heart that will withstand a lot of squeezing, holding and pocket-dwelling. I only use pure wool felt and all hearts distributed by 1000 Hearts are made from it too – it’s the only thing I’m really fussy about.
Stuffing: I started out using synthetic stuffing which you can get at craft stores. However, in the spirit of kindness to our planet as well as the people who inhabit it, I prefer to use natural fibres. You can get wool and eco stuffing from specialist stores and online.
Thread: If you’re using six-strand embroidery thread, I recommend using only two strands when stitching your heart (this is what I do). If you don’t want to split the thread, the single strand perle cottons work well and can be easier for groups, young Heartists and beginners.
