I have done the cake stand in red, using the back stitch and the double knot stitch for the top rim of the cake stand.
For the cake, I am doing the back stitch using three strands of pink cotton floss. For the frosting decorative border I am using three strands of satin floss. It is really beautiful! I am using the couching stitch with this, to hold the strands in place and give the border a draped look. In between each draped element, there is a round shape and I am using the satin stitch to fill those:
I was having a hard time doing the satin stitch with this satin thread :) the thread kept slipping out of the needle and it was becoming very frustrating. I remembered that I had some smaller needles that have a smaller eye so I switched to this size 28 chenille needle. It made all the difference! I had been stitching with my size 24 chenille needle - you can see the difference between the two - the top is the 24 and the bottom is the 28:
The 28 really holds the satin floss better. Since the 28 is shorter I find it easier to work the satin stitch. Here you can see the two needles threaded, I am using only one strand of the satin floss to do the satin stitch.
I will be sure post my pictures as I make more progress on this one!
