Thank you feline fanatic for your reply.
I will be doing one shirt block at a time, they will NOT be joined into a quilt when at the embroidery machine. The quilted blocks will then be laid out by GD and make filler blocks as needed. Then finally sewn into quarters to clip/fringe seams before becoming a fully sewn quilt.
The shirt designs are simple inked ones and a few are a bit heavier. Already planned to work around those designs with sewing machine.
I will do an online search to see if any information is out there.
