This is a labour of love! You are so creative with the hexies.
I started doing them for a charm quilt and ended up with 2400 - which- because they are larger than yours, is way too much for a single quilt. So I'm turning them into two quilts. The basting is a favourite pastime and very mindless and therapeutic. I thread around 10 needles and baste until they are all used before threading again. I have convinced myself that this does not break the sewing rythm so often. I use the same threading trick for sewing them together, but find it difficult to drag the quilt around once it reaches a certain size.
