Changing Colour in Crochet- this method allows for a neat change from one colour to another in your crochet work. It is not necessary to fasten the first ball off, it can be just left aside for a few stitches or rows during the course of a multi-coloured pattern.
Step 1: Work up to the final "yrh, pull through"of the last stitch in the old colour then wrap the new colour around the hook.
Step2: Use the new colour to complete the stitch.
Step 3: Continue crocheting using the new colour.The Knitting Wool Store Crochet Techniques Changing Colour in Crochet
