I followed instructions from Salmonmac, and I am happy to say, my first bunny bootee is finished and looking good. I'm now half way through the 2nd bootee. Many thanks for your help everyone.
I don't like Debbie Bliss patterns, she isn't very clear in her instructions and doesn't tend to update stitch numbers which makes it a nightmare for beginners.
However I did do this bootie pattern of hers.
At this part of the pattern you should have a total of 12 sts left on your needles after all the decreases (6 for the sole and 3 each side of this.
Keep the 6 sole sts on one needle, transfer the 6 sts (3sts either side) from each side of the sole onto a seperate needle and do a 3-needle cast off and voila!
