HD 6600C Stitch Applications Guide
Included Accessories ($100 value)
Stitch Applications (215) - A Stitch Application simply means a specific sewing technique that you can do with a selected stitch. Basically, Stitch Applications are all the different things you can actually DO with your machine!
One-Step Buttonhole (6 Styles) - Buttonholes are sewn in one easy step. Just place the button in the buttonhole foot and the machine sews a buttonhole perfectly sized for that button, delivering consistent results every time.
Built-In Needle Threader (+) - Effortlessly threads the eye of the needle - eliminates eye strain and saves you time.
Top Drop In Bobbin (+) - Easy to thread and easy to see! The transparent bobbin and cover allow you to monitor your thread supply so you don't run out of thread in the middle of a seam.
Drop Feed (+) - Feed teeth can be lowered for button sewing or free-motion sewing - a must-have for quilters! Simply slide the Drop Feed Lever to lower the feed teeth. Slide it back and turn the handwheel one full turn to raise the feed teeth again.
Touch Button Stitch Selection (+) - Select your stitch with a simple touch of a button - the optimum stitch length and stitch width are preselected so you can start sewing faster, but stitch settings can be adjusted as desired to customized for your projects.
Adjustable Stitch Length (+) - Customize the appearance of a stitch by increasing or decreasing the distance between stitches. Use this function for various stitch techniques like applique, basting and more.
Adjustable Stitch Width (+) - The size of the stitch from left to right is adjustable, to make the stitch sew narrower or wider as desired.
Heavy Duty Metal Frame (+) - The machine's interior frame is metal, providing long lasting durability.
Stainless Steel Bed Plate (+) - The surface of the machine's arm is made of stainless steel, providing a smooth surface that allows your fabrics to glide smoothly as you sew.
High-Performance Motor (+) - The machine has a motor that is 60% stronger than a standard sewing machine motor, allowing you to sew at higher speeds up to 1100 stitches per minute.
High Speed Stitching (1100 stitches/min) -
Professional speed for faster results.
Needle Up/Down (+) - Select the needle's stopping position on demand.
LED Lighting (+) - Long lasting LED lighting provides bright illumination and stays cool to the touch.
LCD Screen (+) - LCD screen clearly displays your selected stitch as well as stitch settings for length and width.
Free Arm (+) - Slide off the Removable Storage Compartment for access to the free arm, making it easy to sew trouser hems, sleeve cuffs and other smaller or tubular projects.
Sewing Space (Needle to Tower) (6.4") - The distance between the needle and the main part of the machine. Having a generous "C" space allows you to sew larger projects like quilts with ease.
