Janome Coverpro Serger FAQ
Q: I have heard people say they have stippled their quilts using a CoverPro; how is that done?
A: This is a new trend becoming more and more popular among sewing enthusiasts. Set up the CoverPro for a Chain Stitch (one needle and the chain looper). Place polyester thread in the needle and cotton quilting thread in the chain looper. The needle thread should match the quilt top or coordinate with the different fabric colours. The cotton quilting thread should match the quilt back. Channel stitching (also known as stitch in the ditch) or Random stitching (also known as stippling) can be done easily on the CoverPro because of the large opening between the head of the machine and the needle. The chain stitch on the back will be decorative, and will add just the right touch to a new quilted treasure.
Q: When using either my CoverPro or my serger I just can’t seem to go around an outside curve with out the fabric bunching. What can I do to avoid this problem?
A: On the serger, when you first start to notice the fabric is puckering or waving, stop. With the needle(s) penetrating the fabric, slightly life the presser foot to relax the fabric, lower the foot, and then continue serging. I say slightly, because if you lift the presser foot all the way up to the tension release position, it may cause skipped stitches.
On the CoverPro, sewing on the curve with the Chain Stitch resembles regular sewing, because only one needle is used to form the stitch. With the Cover Stitch, where either two needles (900CP) or three needles (1000CP) are required, only one of the needles needs to penetrate the fabric before lifting the presser foot. In addition, slightly increase the stitch length and serge slowly. In most cases, stitching an outside curve with the CoverPro is easy.
Q: Is it possible to do puffing (gathering on both sides of a strip of fabric) with the serger or CoverPro?
A: Yes! In fact, this is one of my favorite techniques for both the serger and the CoverPro. Puffing is used frequently in heirloom sewing but is also great for home dec projects. I created a project using this technique called the Puffing Pillow (visit the project archive section of www.janome.com for complete instructions).
Set up your serger for either a balanced three-or-four Overlock stitch. Place all-purpose serger thread in the needle(s) and loopers. Adjust the needle thread tension approximately three numbers higher than the normal setting. The upper looper and the lower looper do not need adjustment. The stitch length and differential feed should be adjusted to the highest number possible. Please note that some sergers will decrease the stitch length when the differential feed is adjusted. This is acceptable. The stitches may appear loose or uneven, which is expected. Stitch alone one side of the fabric strip and then stitch along the opposite side. The gathering of the fabric at each edge will create the “puff”.
When using the CoverPro to create puffing, it is not necessary to adjust the thread tensions. The differential feed and the stitch length should be set at the highest possible setting. If the gathering is not full enough, stitch again right on top of the previous stitching.
This technique can be repeated in several parallel rows across a larger section of fabric, creating an interesting, textured look to the fabric.
Q: I’ve heard you should use wooly nylon thread in the needle(s) when serging on spandex or Lycra fabrics. Is this correct?
A: Wooly nylon is often used when making swimsuits or working with lingerie. The main reason is the softness of the thread; it’s not irritating to the skin, wet or dry. In addition, the stretchiness of the thread allows for garment ease and recovery, meaning when you sit down and get up again, the garment stretches with your movement then reverts back to its original shape.
Q: Is serger thread the only type of thread that can be used in the CoverPro or serger?
A: Not necessarily. There are many types of thread that can be used with stunning results! Embroidery thread, cotton quilting thread, metallic thread, monofilament thread, and heavy decorative threads are often used in the CoverPro and sergers. The type of thread you use will determine where it will be used on a serger or the CoverPro. Heavier threads are suggested for the loopers only. It is also necessary to use spool caps and sponge disk bases with the smaller “spools” of thread, especially ones with rough edges.
