This is from 11/07/17, so not a new question.
What ECS would reply, I do not know. Most patterns for cross stitch can be adjusted to enlarge or shrink, depending on the stitch count, but I am not clear about stitch count, fabric count for an afghan.
KRISTI FROM ECS WILL SEE THIS ON EITHER 11/24, FRIDAY, OR ON 11/27, MONDAY.
