Thanks to Sam Hunter for putting this great Blog hop together....
Having taught so many improv classes, one question always comes up...
When you improv piece, you don't have to worry about 1/4," right?
wrong. I always use a 1/4" seam.
Anytime I sew I sew a 1/4" seam... (unless a pattern stated otherwise)
Just like in any piecing, a 1/4" is valuable and important... Think about it like driving a car, Do you want be swerving in and out the yellow and white lines on the road?
(in sewing, driving 1/8" to 1/4" to 1/2"?)
No. You want to keep it straight... 1/4" all the way...
It's the same, sewing improv or regular piecing.
If you want you fabrics to lay flat, learn to sew a 1/4" seam.
So, let's look at that Quarter inch seam...
I have found that many people are not aware of where to place their fabric under there presser foot for a 1/4" seam. So let's find it, shall we?
I have this hand 1" acrylic ruler,
I can place it up to my needle, and see where the 1/4" line appears... It is just shy of the #7 line on machine.
So if I sew with my raw edges just showing over the edge of my presser foot, I can sew it, and test it, by measuring it again with the acrylic ruler.
Every machine can be slightly different... So it is valuable to know this info.
Regular piecing in quilting:
Patterns are most often drawn with a 1/4" seam allowance. (Unless otherwise stated)
If you are sewing at a 1/8" or 3/8", your blocks will not come out the right size...
Your points won't match easily.
I hear this over and over, "how do you get your points to match?"
Sewing a quarter inch seam, will give you amazing results.
Another way to look at a 1/4" mark to make your 1/4" piecing correct... When you are piecing, and you have (in the situation above) a square and a diamond... Where do you line it up?
Do you lay the point raw edge to raw edge?
Nope. ( underneath, you won't have any fabric when you start sewing because of the angle)
Let's look at this below...
When you have an angle, and a straight edge... your fabrics need to overlap by a small amount... Now. Many times when I'm teaching people know the right words to say... they say, " it should stick out a 1/4"...
Well, not really.
What you are actually looking for, is where the TWO fabrics intersect when laying right sides together. Where they intersect, that point, should be a 1/4". That purple tiny triangle you see is not actually sticking out a 1/4", it's less then that, but where they "MEET" ( which you can see with the ruler laying there, is exactly a 1/4". THAT is your sewing line... Your quarter inch seam allowance...
So when you sew that now....
...and you open up your fabrics, they meet exactly...
Oh, one more thing I learned from teaching is many people don't know the term, "DOG EAR"...
That little triangle that sticks up over your sewn seam, is the dog ear... you can trim that off, so the seam stay flat, and that little extra bit of fabric, won't get curled up in your seams and make that bulky thingy in the back of your nicely pressed blocks....
And the same thing happens at the other end...
OK, makes sense right?
Let's look at it again, so it's crystal clear...
Let's go to the extremes...
This image shows the fabrics intersecting at 1/2".. that is not the 1/4" seam allowance we want... This sort of seam will make you blocks smaller then the planned finished size..
This image shows the fabrics intersecting at 1/8" aprox...shy of a 1/4"... not the 1/4" seam allowance we want... Sewing this seam will make your blocks finish larger then the planned finish size...
A perfect 1/4"... This works for any block, that has two different angles meeting... it happens in HST's ( half square triangles ) Diamonds, triangles, curves etc...
So! Your best bet for great results in your quilt piecing, is to learn where your 1/4" is on your machine.
Have a hard time keeping your fabric under you needle, in the right place?
Find your 1/4"(as shown above, first image) , grab some painters tape,
and run it all way across the throat of your machine... ( from the needle straight towards you...)
Then as you sew, you let the fabric ride the edge of the tape...
other possible issues could be:
quality of your machine,
Are you pulling you fabrics when you sew? (to the left or right)
Do you have a table that is flush to your sewing throat? Draping the fabric over the edge of the machine, can fight you as well, when sewing a 1/4" seam...
15 Minutes of Play, right?
15 Minutes to learn, practice and master your 1/4" inch seam.
:-)
Don't forget to trim your dog ears... woof!
