Bolivian Knitters Help Heal Hearts

The indigenous Aymara women of Bolivia have knitting as part of their heritage, but now they are able to use old skills in a new way by helping make medical devices to save the lives of children born with holes in their hearts.

The device, known as Nit Occlud, was designed by Franz Freudenthal, a cardiologist in La Paz. It looks like a little top hat knit out of wire and can be made in different sizes to block a hole in the heart.

It’s made of nitinol, a nickel-titanium alloy, and can be collapsed and inserted into the body through a catheter. It’s only expanded when it gets where it needs to go, making the procedure minimally invasive and inexpensive, which is a must in Bolivia, the poorest nation in South America and a place without enough cardiac doctors to treat kids with heart problems, which can also be more serious in the high altitudes.

It takes about two hours working in a clean room to knit a device, and knitter Daniela Mendoza told the BBC she’s glad to be able to help.

“We are very happy, we are doing something for someone so they can live,” she said.

Getting ready for back to school makes me think about pencil crafts, so let’s take a look at some pencil themed knitting patterns!

I recently made a pencil on a circular knitting machine, and it was a fun, quick, easy project that uses little bits of leftover yarn (and if you don’t have yellow you can make it a colored pencil using whatever color’s your favorite). And if you want to make a bigger version check out this pattern from Orange Olive Road on Etsy.

If you want to knit a pencil pillow by hand, check out Sketchy, available on Ravelry from Shana S. Cohen. This one uses worsted weight yarn and has two size options and the choice to make a pencil with an eraser or a colored pencil.

Pencil scarves seem to be the most popular kind of pencil knitting pattern, and there are lot of cute ones. This one from Cosy Craft UK mostly uses garter stitch, with some welts to add texture and what looks like an I-cord edging. It calls for DK weight yarn.

If you want to go all garter stitch try this version from Emsley Co Creations, which uses five colors of DK weight yarn and just a little shaping to make the point of the pencil.

There’s also this fun, mostly stockinette so it looks like it curls a bit, pencil pattern that looks like it’s worked in chunky yarn from Little Knits Studio. This one uses just a little garter stitch and easy shaping for the point.

If you don’t want a pencil scarf, how about some pencil socks? The No. 2 Pencil Socks from The Yarn Enabler are available from Ravelry and use five colors of sock yarn. They feature wide ribs to mimic the texture of a pencil and have options to be worked from the top down or the toe up.

Needs Sharpening by Alexander Walker is a free pattern on Ravelry that uses five colors of sock yarn to make a sort of shortie sock. The little bit of black at the tips of the toes inspired the name. These, too, can be worked in either direction and are available in three sizes.
