Lets face it who of us sits down to our machines and thinks how sloppy or how to cut off points, or think I'll do 1/2 inch seams to go with all the 1/4 inch seams I've done so far. Some days things just turn out better than on other days, so I make what I call "planned overs" extra blocks so when putting them together I use the ones that fit best, then make a small wall quilt or a nap quilt,( one that is on top of quilt at the foot of the bed that you can nap under with out unmaking the bed.) or I can make hot pads, what ever the blocks will not go to waste. We all do the best we can, and thats a very good thing, after all I tell my class "in quilting nothing is written in stone"
