This is basically what I do - rather than rant and rail and rave and rage about the foot and the seam allowance - this is SUCH a simple, basic, easy to do solution - although it DOES call for making a sample WITH THE FABRICS AND THREAD YOU PLAN TO USE FOR THE PROJECT- which takes what ? maybe 10 minutes max.
As Holice and others have said - even if one was using EXACTLY the same foot EXACTLY the same way - different fabric and thread weights will work up differently. One size/method does not fit all.
Sometimes one just has to adapt a bit to get the desired results.
