Tetracuspid Hypocycloid Crochet Pattern

This pattern makes tetracuspid hypocycloids.  Ah, What?!  You know the little star-like symbols on the Pittsburgh Steelers logo?  Those are tetracuspids hypocycloids, also known as astroids, also known as paracycles, also known as those little colored stars on the Pittsburgh Steelers logo.  There is even a mathematical calculation to that funny little shape.  Alas, you are not here for me to explain mathematics, you are here for crochet patterns.

This pattern can used to make appliques to add to another project but what I have in mind is for these to be a set of coasters.  I made these in the Pittsburgh Steelers logo colors but these could be made in any color.  You need something to set your Yuengling down on when you are watching football, right?


This pattern uses US crochet terms.  I used worsted weight yarn and size G crochet hook.   If you have any questions about this pattern, leave me a comment and I will do my best to help.

  7. Weave in ends and block lightly with steam iron,
     [note] Since the cluster is so many stitches in a single stitch it will most likely be covering the first stitch of the sc2tog.  Be sure to pull the cluster back to expose that hidden stitch.

Halushka Recipe ~ Braised Cabbage and Dumplings

Image
This recipe is very popular in Pennsylvania where my family is from.  There are slightly different names and slightly different recipes but basically halushka or haluski is a braised cabbage dish with either noodles, pasta or dumplings and sometimes bacon, ham or smoked sausage added.  It is sometimes a side dish but most often it's a main dish.  It is a common potluck dish. In my version I use bacon and drippings and homemade dumplings.  Most recipes will call for cooked wide egg noodles, kluski noodles or bite size pasta like farfalle (bowties).  Instead, I like to make dumplings because they are delicious and because its more likely that I'll have a cup of flour and an egg on hand than a bag of noodles.  Either way it is a quick, easy, inexpensive and delicious dinner. If you want to omit the bacon you can substitute butter for a vegetarian version or use olive oil and an egg-free pasta for a vegan friendly version. I hope you give this recipe and try and I hope that you lov
