There should be a pdf file with the design with steps. You can also run through each step of the design on the EMB machine without stitching.
Typically, hoop no show mesh. Lay down background batting and cut to size as indicated on the tack down stitches. Then lay down trapunto batting and trim to size. Then lay down the background fabric and stitch out the design, stippling etc.
The machine will tack down the background. Keep it ITH. You only remove the hoop from the EMB arm. Do not remove the fabric/batting from the hoop until completely finished stitching.
Trim the block to size.
I mark cross-hairs on the background fabric in case of hoop mishaps. Easier to re-hoop and re-position.
