12.2 Velocity Results … Finally!

February 12, 2011

Thanks for all 5 of you that participated in

I learned a few things about myself when hosting this type of event, which I will share on the next podcast.

Here’s my bullet list of what I learned:

  • get a great giveaway item
  • show the item for the giveaway first to help with participation
  • don’t make a giveaway so complicated!
  • don’t make a giveaway a really long time frame
  • giveaways that seem complicated just get put off until later … and later …
  • give a hard and fast deadline to when the results will be given – no excuses
  • set a timer to help you get past the fact that figuring out the results may seem hard (even though it’s not)
  • once you get past the initial inertia of figuring out results, it is NEVER as hard as you think
  • you forgot how much joy you have in creating the giveaway to begin with if you never work on it!
  • dimensional analysis will get you through times when you haven’t done the math right

… You want actual results?

How fast do we sew?  Really?

Here’s a copy of the pdf of the google document that I created.

velocityexperiment-2

Here’s the picture (for those who don’t have pdf readers handy):

This is not meant to be a display on who can sew fastest when, so I blurred the names here, except mine.

The highlighted column ends up being the speed in yards / minute as I have calculated.  I hope I got all the kinks worked out on the yards / minute calculation.

(note: there are 3 feet in a yard, 12 inches in a foot, and 60 seconds in a minute, and forgetting one or all of these facts can cause you to go crazy for about a half hour)

Actual conclusions (to the data, not to how I mishandled the giveaway and experimental results).

  • Two quilters sewed faster when sewing full length strips rather than sewing blocks.
  • One quilter sewed faster when chain piecing blocks than sewing full length strips
  • MY speed was the slowest of them all when it came to sewing blocks.  And right now I can’t remember if I actually sewed two pieces of 2 and a half width blocks instead of one piece.  If I sewed a length of 5 inches instead of 2.5 then my speed would be much closer to the speed of sewing everything else.
  • Sometimes cats, ironing, threadies under the fabric get in the way and slow us down.
  • The width of the strips DOES matter on speed.  The narrow 1.5 inch strips are slower on all quilters who attempted them, and the fastest speed is on 8.5 inch blocks.
  • Some people get in a rush when trying to time themselves and cause themselves more trouble than they would otherwise.
  • The average speed of all the results is 1.36 yards / minute.  We can sew just about 1 and 1 third yards of fabric in a minute’s time.  And do it accurately.
  • Some people don’t like timing themselves, but everyone who did, I am truly grateful
  • I have a timer on my iPod Nano that I didn’t know I had

Feel free to continue to participate and now that I have the database set up better, I can hopefully reply much faster (get it – faster?) with the velocity.

Giveaway

For the giveaway, I assigned each trial that people timed a separate # and then used the random number generator to determine the winner of the giveaway.

And the winner is:

Janet!

Sending you an e-mail Janet, hope to get in contact with you soon!

  1. Just wanted you to know I enjoy your photography whether quilt related or not you have a good eye and seem to come up with interesting shots. That can be very hard to do.

  2. Great conclusions! I’m glad my mariner’s compass quilt only had ONE block that took THAT long!

    Thanks for the opportunity.


    • when I quick did the math on that one, I was shocked to see how much time it was going to take. Perhaps the other 16ths took less time each?
