some machines have a slightly reduced distance between the bobbin case and the end of the arm. The only cure is to reduce the height of the design or perhaps place it lower on the cap, if possible. And of course changing cap brands may improve this situation as well. With some models of machines, the pressure of the sewing arm against the inside top of the cap is enough to "pop" the entire sewing frame loose from the machine, a nightmare in itself. Along these same lines, different machines have different methods of installing mounting brackets which mate to the frames and hoops. For example, if you are converting from flats to caps, you may to remove certain physical brackets and screws, then replace them with different brackets and screws. Occasionally, you may forget a screw, not tighten a screw, or overlook a firm seating for the brackets being installed. Once again, sewing quality will be affected. Along the same lines, you may have to change out needle plates depending upon whats being sewn. The wrong needle plate or a loose one can cause quality problems as well as thread and needle breaks. Finally, there may be physical obstructions that limit hoop and frame movement. Maybe a loose object has fallen into the path of the hoop travel, blocking it or limiting it. (Ink pens are a major culprit.) On most machines, the sewing head attaches (vertically) to the sewing table. This of course is a built-in limitation for how far the hoop can travel vertically. However, most machines will allow sewing movement right up to the base of the sewing head. But if something falls into the space between the top edge of the hoop and the sewing head, it further limits or blocks the vertical movement. And, depending upon the machine, this may not cause a crunching, grinding noise, so you don't realize when it's happening. One common obstruction is the garment itself. Big, bulky items such as jackets and overalls, may have sleeves that flop over into the path of hoop travel. Likewise, bulky items may catch on the needles, pressor feet, or trimmer assemblies, any of which can limit proper hoop movement.

Though not difficult, it proves quite challenging to inexperienced Embroiderers. And it can have a major affect on the quality of the sewing. There are several key factors to understand: choosing the proper hoop, applying equal hoop pressure for the garment, selecting the proper backing and use of topping. The first step with hooping is to choose the correct hoop. In general, choose the smallest hoop possible for the design. But don't go too small. Be sure that there is ample room within the confines of the hoop to sew the design. And don't forget that includes room for the pressor foot! The larger the hoop, the less support it offers for the fabric being sewn. With less support, you will encounter more flagging (bouncing up and down of the material while sewing) and more shifting of the fabric. www.hsi.us care@hsi.us 173
