No free software unfortunately, but I already use Embrilliance Essentials.
I have now also bought the Premium upgrade pack, so have two new, wider, hoops, one is 300mm x 200mm, and the other is 200mm square. I ordered it from BSK, who rang me the next day to say that although they should have had one in stock, but it had gone missing, so they were getting Brother to deliver it direct to me, could be two or three days so she'd refund my delivery charge - it came the next day. What great customer service from them both. I can't wait to have time to actually play with them!
