One thing is to make sure that none of the garment falls between the hoop and
areas of the machine, where the garment could impede the movement of the hoop
for stitching out the design. When designs are quite large and cover a big area
of the hoop, the hoop may need to come up right against the machine to accomplish
the stitching out of the design. It may take manually holding the garment to keep
it from getting in the way of the hoop movement. SEE DIAGRAM with EXPLANATION.
On a home embroidery machine, in order to stitch out a large design,
or one that fills the whole hoop from left to right, the hoop has to
shift so the right side of the hoop moves towards the inside arc of the machine.
SEE RED ARROW. If the garment or test sew fabric falls between the right edge
of the hoop and the machine inside are, it can prevent the hoop from moving
where it needs to go, causing detail lines and/or fills to be off.
It is best to analyze just how the garment will rest on the machine when it is hooped.
Consider possibly rotating the design and garment and hooping it in such a way that
most of the garment rests to the outside of the machine.
Another thing to evaluate is if the garment or fabric was actually hooped for the
embroidery application. Sometimes backing is hooped, sprayed with adhesive, a
garment is affixed to the backing and the design is stitched out. When a design
is large with detail and has a lot of fill stitching, the "push and pull"
embroidery phenomenon will pull the stitches in with the direction of the stitching
and push the stitches out at a right angle to the stitching. When the detail comes down,
if there is a considerable amount of fabric used up by "push and pull", the detail
lines may be off. For this reason, it is important to actually hoop the garment or
fabric when applying large designs consisting of full fill with detail.
