Oh, the geekery!

I don't think it's possible to be too geeky with the knitting, do you?


Can you guess what they are? These were made for a friend, who will use them for training and education purposes. With children, even!


DNA helix
Yarn: various bits of leftover aran-ish weight yarn
Needles: 3.5mm dpns
Pattern: Kimberly Chapman's ingenious Baby's First DNA Model

Notes: Well, what can I say, it's a DNA double helix model. The twist is knit right into the backbones, which is awesome. I did ignore the directions for making the base pairs. Putting the whole thing together required more than the standard number of hands, but I eventually managed it. It's a great pattern, and, as I said, ingenious.


Chromosome
Yarn: some leftover Rowan Pure Wool and DB Cathay (I think)
Needles: 3.0mm dpns
Pattern: just two circularly-knit tubes

Notes: This was pretty easy to make. I chose random numbers of rounds for each stripe, stuffed it as I went along, and stopped when I got sick of changing colours. I used Techknitting's jogless stripes method, which works very well. There're a few bits where I wasn't careful about carrying the non-used colour up and a few loose places where you can see a bit of the stuffing (if only I could have found dark-coloured stuffing), but on the whole, pretty good.

The other thing about the chromosome is:


It un-snaps at the link! My friend wanted to be able to talk about crossovers and be able to show a bit of how it happens, so I made the chromosome "openable" to show separation in meiosis. (Or, at least that's what I remember from AP Biology.) It's just a normal snap button closure. If I had more energy, I could have made a few chromosomes, with bits or lengths that unsnapped or un-velcroed that could be exchanged, but you know, there's only so much I'm willing to do.

love it!
those chromosomes are genious. and that DNA model is on my long to-eventually-knit list!
Lucky friend you have there.

Those are crazy!!! The other thing that would have worked would have been magnets inside sewed on the outside. Very cool that they are being used for school though!!!
