Deciding Which Hoop Size Is Right For You

For optimum design registration, it is important to use a hoop that is closest to the size of the design. This will help eliminate puckering as well as wasting other supplies, such as backing or topping.

Needle Spacing Guide

We thought it might be helpful to share a simple way of determining needle spacing or sewing field. The easiest way is to measure one of your current hoops from the tip of one metal stamping to the tip of the other. Another way is to measure the distance between arms on your tubular machines. Here is a list of conversions from millimeters to inches for the needle spacings that we carry.

Am I sewing flat or tubular?

Determining whether you are embroidering flat or tubular is the first step in deciding which hoop is right for you. Generally speaking, most tubular embroidery is sewn with the machine table dropped or removed so that the garment may hang freely around the bobbin arm. The entire hoop is removed from the machine when each garment is completed then re-hooped with a new garment.

Flat embroidery is sewn with a spider hoop setup. The adjusting ring and inner ring are hooped and inserted in the spider frame, which remains attached to the machine. All flat sewing is done with the table in the "up" position. There are certain instances, on some machines, that tubular hoops may be used with the table up.

Durkee Enterprises' primary product line includes only tubular hoops at this time. However, flat customers may need to replace the adjusting ring only. Durkee Enterprises supplies unbreakable adjusting rings that are compatible with most flat, spider setups. Please call for details. Please do not hesitate to contact us if you are unsure whether you are sewing flat or tubular. We will be glad to help.
