The design you choose plays a large part in how the shirt will drape when the embroidery is finished. If you choose a design with very dense stitching and the design is large enough to take up a considerable amount of the garment, it will affect how the garment hangs. Start with things like red-work designs, similar to the apple basket embroidery shown in the photos, that are not dense but will give you the opportunity to experiment with hooping and stabilizing options. Stabilizer plays a major role in machine embroidery. My personal favorite for machine embroidery on tee shirts and sweatshirts is a woven heat-away stabilizer. This stabilizer will vanish when the stitching is done but is less apt to stretch or flex while the shirt is embroidered. Many people prefer water-soluble stabilizer. The water-soluble stabilizer also vanishes when the design is done. The advantage of a stabilizer that vanishes is that there is less stiffness added to the design so only the design itself is changing the way the shirt will drape. There more and more stabilizers becoming available to the home machine embroidery market all the time. Take the time to shop around and experiment to find a stabilizer that works well for you with your embroidery machine. Always wash the shirt before you embroider it. This allows the fabric to do any shrinking before it is embroidered. The embroidered designs are not going to shrink with the fabric of the garment. If the shirt shrinks after the design is embroidered, the design will most likely pucker and you’ve wasted time and thread. Here’s the step by step way to have successful machine embroidery on a tee shirt or sweatshirt.
Press the shirt, so it is wrinkle-free but do not stretch out the shirt while you iron it.Try the shirt on and mark the placement.Turn the shirt wrong side out.Spray lightly with a basting or temporary adhesive spray.Smooth one to two layers of stabilizer on the area that will be embroidered.Turn right side out.Hoop the tee-shirt, be sure you are not stretching the shirt while placing the shirt in the hoop or while you are tightening the hoop.Check the placement. If it is not exact, totally remove the fabric from the hoop and start again. Do NOT pull and stretch the shirt into the correct position.Attach the hoop to the machine and make sure only the part of the shirt which is going to be stitched and that the rest of the garment is clear of the hoop.Follow your embroidery machines manual to test the stitching area and stitch out the design.
