Here is something I never heard before... My mother took a class and was told by the instructor to keep working on her quilt blocks with the portable machine she took to class. She has another machine set up in her sewing room which would be easier & more convenient to work on at home but the instructor said the blocks may not be consistent in size from one machine to another. She has a lot of time, money, and effort into the quilt so she continues to work on it with her portable. Has anyone else ever heard of this theory or has anyone ever experienced problems because of working on more than one machine? I would think that you could take your blocks from class and compare your seam allowances, then, if needed, set up your other machine's needle position to be the same. Any thoughts?
Well, from my own experience, I would say that it is true. You need to use the same machine. I had started a quilt for my daughter and then put it away. I got it back out recently and made another block. The block came out smaller that the others and I couldn't figure out why. I asked my daughter what she thought and she said that I had used my Singer featherweight to make the other blocks and that I was using my newer Singer to make the last block. After thinking about this for some time, I'm pretty sure I had my Little Foot attachment on the Featherweight and I didn't use it on the newer singer. I'm going to change the foot on the newer Singer and see if that makes a difference. Hope this helps.
Debra - this can be true if you are using different feet to get your 1/4" from - if you don't use that 1/4" foot though and are old school - using either a mark on your sewing table or your mature eye to see this then I see no problem using different machines... but the feet are not all consistent.
i switch back and forth, but i know where that scant quarter inch seam is on all my machines.

I'm guessing its all in the feet. I can't see why it would be the machine. A test block woud let her know whats what with the seam allowance.
This is very true unless you know your machines well. When a my friend and I were working fervently to get a quilt done for her parents anniversary we were using both of our machines....and disaster struck!!! The stitches and the way the machine pieced the fabric together were completely different! When we tried to piece the blocks together they were different sizes and you could really tell. I think it had something to do with how (difficult to explain), much fabric the bottom piece took when attaching it to the top. Needless to say we ended up "unsewing" every block I did! And had to re-cut some pieces because they were stretched. Never do that one again!
Tell your mom to piece with one machine, but once the inside is done I think it will be ok to add borders with another.
Debra, I think it makes sense. I wondered, keeping that in mind, if you could compare blocks made on both machines for consistency in size and make necessary adjustments on the machine you would be doing most of the work on. If not, I would be reluctant to start a quilt in a class on a portable machine since it's more convenient to work on the machine that is set up in a cabinet with more work space.
