I have been crocheting for a very long time.... however, I have recently taught myself how to knit... just the basics. I have a beautiful dress pattern that I would like to try... But it has an unusual twist... part of it is crocheted and part of it is knitted. The instructions are very clear that you do not cut the yarn and to pick up stitches on the knitting needles then change back to the crochet hook.... Can any one explain to me how to do this.....????
