Some of you are wondering why check your seam allowance, I have a guide on my sewing machine. Well, every machine is a little different. It's always a good idea to check. Once I start sewing a quilt on my machine, I do not switch machines while working on a quilt. (I have three machines, 'Lucy', 'Ethel' and 'George') Believe it or not, there can be differences between machines too, ever so slight... but depending on your project, it can make a difference. Here is how I check my quarter inch seam.
|In this photo my seam line is just outside the 1/4" mark... it doesn't seam like much...|
But, my two blocks should measure 2 1/2" and look... I'm an 1/8th of an inch off..
In a block that has several 1 1/2" blocks sewn together, an 1/8th of an inch adds up quickly.
|Here my seam line is just within the 1/4" mark....|
|My two blocks measure 2 1/2" exactly.... Perfect!|
So the moral is that 1/4" seam really counts. It is worth the time to measure it from time to time so you know exactly where you need to line your fabric up so that you have the perfect 1/4" seam. There are many seam allowance tools available in quilt and hobby shops, and they are all wonderful. So remember to check those seams and have a wonderful quilty day.
