Wherever possible, I do not cut the yarn at all. In the very rare case where that might be necessary, I will contact you before going anywhere near scissors.
I will return the yarn to you hand wound in your choice of a skein or a ball.
I have no allergies that I am aware of, so will work with any fibre (though please be aware, yarn with a halo runs a slightly higher possibility of needing to be cut. I will do anything I can to avoid this).
Customer pays postage. Stated timescale begins as soon as I acknowledge receipt of yarn. I drop completed untangle jobs to the post every week on the Wednesday following completion (unless you need it sooner, in which case, please talk to me - I'm sure we can sort something).
