I have learned to read the 'distructions' as my DGD calls them. Sometimes a picture is
not worth a thousand words and the pattern designer might actually know a better way.
I have learned to put the pattern, extra fabric and any pertinent notes about a top or UFO away
together!!
I have learned that I have a Pavlovian response to challenges. This is not always a good thing--altho it has stretched my abilities and taken me in many foreign directions. And won a few fair ribbons

I have learned that I like the feelings that come with selling a quilt (or top) especially if I sell it to a fellow quilter that I admire. Wow! What a rush!!
I have learned that sometimes being my own worst critic is a good thing, because it forces me to put out the best effort I can, and is a bad thing because it costs me time. And could someday lead to recognition...or an ulcer.
And finally...there are times to sew and times to rip. All part of the process.
