There are a number of reasons you would want to have a Baby Lock products registered:
The BL 6700 would be the best machine. It has several great features that make it both a good "learning" machine and a addition to your sewing room.
Increase your stitching speed, decrease your tension, and lengthen your stitch. Experiment with the settings and speed until you get 'the hang of it' and the desired results.
We have a great and Bonus Sew at Home OnDemand (pre-recorded) class just that subject and is called "Free Motion Quilting with your Baby Lock?"

Note you will need to set-up an account on this website, even if you have a Baby Lock website profile, they are different.
If it is a technique such as stippling or free motion embroidery you will need your hands to guide the fabric, using the foot pedal is usually the best. When doing simple seaming, you do not have to guide the fabric as much, using the "Start/Stop" button is very convenient. When you need more control over your fabric using the foot pedal is always the best idea. Keep in mind, when using a machine with an embroidery unit attached, you will need to have the foot pedal disconnected.
Select a buttonhole where the stitch length is not extremely tight or dense. Then, be sure to stabilize the area you will be stitching your buttonhole to avoid any excessive stretching.
Since the thread you are using in the needle will be a slightly thinner and finer texture thread, you would need to tighten your upper tension to compensate the difference.
Use the walking foot when sewing velvets and velveteens. That will help prevent the sliding or crawling of the fabric.
First, you should be using a water soluble stabilizer/topping on the top of your fabric along with your regular stabilizer underneath. This will give a smooth surface for the stitches to form on. Click here to check out the Baby Lock stabilizers.
If you are using a water soluble stabilizer and still having this problem, increase your density a little, depending on the size of the design area you are filling. A larger area can handle more density than a small area.
