The variations are what distinguish it from machine work. It's beautiful.
My Pfaff sews what I tell it to sew. You can program imperfect-looking blanket stitches, for example, up to 120 different ones, just by copying the last thing you did that looked truly imperfect (speaking for myself, that is.

)
I'll have to get my machine out and see if I can still remember how to do that. I've done straight stitching for almost 2 years now with those charity quilts I churned out. It's been enjoyable though.
Added some rows around the pink and red quilt started with 3 embroidered quilt squares someone found in the family trunk in an estate. It will be a nice little quilt when done if it looks half as good as my model. Of all things, I tracked the model down online the other day, and it was actually the back of the quilt. ROAR!!! That has to be the best back art I've ever seen!
And all I did today was pull out another group of squares I found on ebay, where someone had done the flowers on this panel, but not the children blocks. I finished up her duckie block by using the same colors one would expect to see on a mallard duck--green head, white ring neck, grayish tan body and blue on the wing, although it may not look much like a wing any more after I sewed stuff all cocklemaimie. Poor lady who sewed the flowers probably expected a more conventional approach to embroidery that my free style. I grow more and more convinced the lack of a dahlia-like flower at the top to correspond with the one at the lower left is why this group of 3 repetitions may have been a factory leftover, with someone just too disgusted to wash & repeat and put 3 blocks with the deficient blocks on a separate pile for factory workers to buy for 2 cents or just take home free, sometimes stuff the factory rejects. That's why there are 3 panels of 4 alike and one unalike, just maybe (not sure). I try to look for clues why I'd get a steal on ebay, and it's fun to figure out why this and why that. I worked in a really picky factory when I was young for one year. Those swimsuits didn't say "Catalina" until supervisor Angie said they could say "Catalina" on them. And there was some truly nice items in the company store of something that may have had such a minor flaw you'd have to be a total expert to figure out why it was there for sale cheap to workers. Their approach to excellence, though never once bothered me. I loved being shown how to make money doing perfect work 500 times a day. I made a game of it most days. They passed quickly. Only one day, I was really bored. I almost left the factory. Glad I didn't. Most days were a lot of fun because you could challenge yourself to a duel, and sometimes that landed you a supervisor visit to put you somewhere else while others caught up with you.
So much for my year in the sewing factory. Oh, yes, I made my first quilt top there. They had a ton of 40s' old swimwear material roughly the size of one foot by two foot "bricks" and I sewed them into a colossal, homey-looking stage curtain for the Christmas melodrama in which employee actors and actresses made fun of the bosses and supervisors with characters in the melodrama being named for this one and that.
The only thing consistent on the block are the previous embroiderer's lovely flowers in pink and purple.Here's my silly mallard ducky who should have been yellow, most likely, to fit in with forties toddlers expectations back then. I really don't know when it was printed, I'm just guessing from the colors the lady did 8 squares with as looking 40s-ish, though I really am just guessing:
[edit --adding 2 more blocks the way they arrived, completely finished.]
[scan 2 is the dog clown block that is finished]
[scan 3 is the elephant block. The elephant is a very pale gray, and it is almost indistinguishable from the somewhat aged percale that has mellowed to a similar color to unbleached muslin. It likely was pure white when new, and it takes about 70 years to age like these squares, another reason I though maybe 40s on these squares. This work may have been left unfinished before I was born. Or was picked up and given to a great grandmother who for some reason couldn't finish it, or a busy mom whose baby was born before the quilt was completed, so with her extra demands, she just put it away until "later," which never came...
It's easy to start a quilt thinking it wouldn't take much more time than a school art project.
