Testing - making samples before proceeding
I don't like to - but I sure could have prevented a lot of aggravations and mistakes if I had done so.
Things to check before proceeding -
Stitch length -
Seam allowances -
Finished unit/block size -
Is the pattern block right - sometimes the directions or pattern is wrong!
Do the fabrics I think will look good together - do they look good together after being sewn together?
Tension -
Pressure -
Anything else that you routinely do - or think you should do?
