FAQ's (Frequently Asked Questions)


What machines does it fit? Will it fit a Pfaff? Featherweight? a Bernina? Viking or Viking/Husqvarna? Janome? Brother 1500? 1300? Juki 98Q?
We have never met a machine it doesn’t adapter to! See the "How to Attach the Curve Master Presser Foot" Guide on this website for specifics.


What are all these feet in the box? Which adapter goes with what machine?
There is one snap-on presser foot (the piece with the wire) and six adapters to fit the standard machine shanks for different types of machines. See the Adapter Guide portion of this website.


Why are there so many pieces in the Curve Master box?
This way, one kit will fit all your machines even if you add a machine in the future. There is the snap-on foot and 6 adapters to fit all different types of machines. We knew a lot of quilters & sewers have more than one type of machine, and we didn’t want you to have to buy different feet for each.  For shop owners this means they do not have to carry a large inventory for each different machine or guess how many of which to order.  See the Adapter Guide for specifics.


I don't need all the adapters. Can I just buy what I need and save money?
The variety of adapters allows you to add a machine later without having to repurchase a new foot for it. This also allows you to take a class at a shop and use their machine, and your foot will fit it. Or you can share it with a friend and it will fit their machine. Actually, the cost of labor to individually pack the adapters and the cost of printing different packaging would increase the cost of the kit, so getting all adapters is the less expensive option!


When sewing, I get puckers, pleats, and/or end up short of one fabric at the end. What gives?
The number one cause of any sewing imperfections is putting the two fabrics together as you sew. KEEP THE TWO FABRICS SEPARATED AS YOU SEW. Keep the top fabric up in the air, do not lower it to touch the bottom fabric. Just be sure both fabrics touch the seam guide as you sew.  I know this is the opposite of what we have always been taught, but there are the Laws of Geometry which apply every time and it will work!  See the "How to Sew with the Curve Master" tutorial on this website.


The ends don't match and they should. What am I doing wrong?
If it is 1/16-1/8” off, it is probably because of putting the fabrics together rather than keeping them separate as you sew. Or it is because of stretching one piece more than another. Relax the pressure with wich you are holding the fabric as it sews, and keep the top up in the air. If it is about 3/8 -1/2” off, it is most probably because of miscutting the fabrics. You cannot cut out a piece and sew it back into the same fabric as this does not include the seam allowance and you will always end up short. You must use templates which include a seam allowance and the outer curve will appear larger than the inner curve. (But the sewing lines are the same.)

We have the Bent-tip Tweezers specially made to fit into the "safety slot", the opening immediately left of the seam guide of the Curve Master.  This allows you to hold onto the fabric, keep both bottom ends together for just the last 1/2" of your sewing, without hitting your needle!  This is another distinction between the Curve Master and other presser feet!  



The fabric does not move under the presser foot. It scrunches up.
Two possible reasons:
1)  The seam guide is the raised “wall” about ¼” from the needle hole. As you sew, the fabrics should just glide along this wall. If the fabric is placed beyond this wall, under the wider portion of the Curve Master to the right of the seam guide, it will bunch up and not sew. So you cannot sew wider than ¼” seam, nor appliqué or topstitch, with the Curve Master. (There is a 5/8” Curve Master available.)
2)  The downward pressure of your machine on the presser foot is too tight. Make the adjustment to decrease the downward pressure per your machine instructions.


How do I cut the curves? Must I use Just Curves templates? Can I use another designer's templates and patterns?
You can use ANY templates and patterns that are accurate. Just do not follow their instructions about pinning and clipping the curves, or putting the fabrics together as you sew. Use the Curve Master Presser Foot instructions for sewing with their patterns and you will get fast results. In fact, in addition to the Just Curves templates, we have tested and sell the Creative Curves, Virginia Walton, Marti Michell, Come Quilt With Me, Kathie Alyce Waterfall and S curve, John Flynn, Cheryl Phillips and other designers products.


Some quilting teachers and template designers say I don't need a special foot to sew curves. So do I really need the Curve Master?
Well, that depends on the enjoyment you want from your efforts.   We don't "need" electricity to run our homes, witness the Amish,  but it sure helps!  Yes, there are some who say that a special foot is not needed with their techniques, and this may be true.  The Curve Master is a new technology that is proven to add efficiency and productivity to our efforts, regardless of what the design is and regardless of who the designer or teacher is. 

I speculate that some teachers have built their careers on teaching "their" special techniques and may now feel (incorrectly) that the revolutionary technology of the Curve Master renders their products irrelevant. Template and pattern designers may believe that a prospective buyer of their products will shy away from purchasing them if they believe they will also have to purchase something else in order to use them.  In reality, ANY pattern or template featuring curves will be done faster, more easily, and with less strain and effort with the Curve Master.  

Here at Just Curves we LOVE every curvy design we have ever seen, regardless of who the designer or teacher is.  (Well, almost every one!)  If you see a pattern, design or template set that you wonder about, ask us!  We have tested many of them and carry some of them.  We are always looking for new products to feature and are delighted to bring you new ideas whether they are ours or someone else's!  


What radius curve can the Curve Master handle? Can it insert circles into holes?
We have NEVER met a curve the Curve Master could not master!  It can do small, tight, hairpin curves like the Hearts and Gizzards design.   It can do long, swooping, shallow curves like the Giant Dahlia design.  And it can insert complete circles into holes, regardless of size-small or very large, for example the Dresden Plate No Applique.  And remember, it is great for STRAIGHT seams as well!  Perfection in piecing!
