Some points to remember from the General Guidelines:
Use Vilene water soluble stabilizer;
Use the same thread for the upper and bobbin to get two-sided embroidery.
DO NOT embroider several designs in one hoop.
Here are the instructions on how to make the Celtic Fish Bowl and Doily Set.
To make the bowl, you'll have to embroider five bowl panels, which is in the first row on the picture, and the pentagon for the bottom.
Use 2 layers of Vilene-type water-soluble stabilizer and use the same thread for both the needle and bobbin to get 2-sided embroidery. Rinse the stabilizer and leave to air dry.
Impotant Note: It's very important to use as small a hoop as possible. E.g. if your design is for a small hoop, use the small hoop, not the large one; if your design is for a large hoop, use large, not mega. Do not try to embroider several freestanding lace designs in one hoop. This is because all water-soluble stabilizers stretch, and in a bigger hoop, it's going to stretch more. This can lead to the design falling apart after the stabilizer is dissolved. It's always better to embroider one part at a time.
If you like a more traditional bowl shape, do not stitch the fins together.
To make this doily, you'll have to embroider six doily panels and stitch them together. Use 2 layers of Vilene-type water-soluble stabilizer. For the doily, you can use white bobbin thread as it doesn't have to be two-sided. Rinse the stabilizer and leave to air dry. Press with steam and stitch the parts together using invisible thread.
