365 Days, 206 Bones, 1 Skeleton

Over the last week and a bit I’ve tackled the arms of the skeleton. The arms were easier to design and cut than the hands as they’re nice and big.  They took a bit of time to sew (2 hours plus) and add stuffing to. I’m happy with how these have turned out.

I won’t be joining these together with stitches just yet as the bones will be too hard to store when they are all together.

Teratoma

I’ve been making Teratoma Tumors  for about 5 or so years.  They are a something that I find both fascinating and horrifying.  Browsing Teratoma images online is not something I recommend or like to do.  It is confronting to see so many babies with Teratoma’s.

Teratoma’s often sell to young women who have had one found on there ovary, a very common place for a teratoma.

From Wikipaedia “Teratomas belong to a class of tumors known as nonseminomatous germ cell tumor (N.S.G.C.T.). All tumors of this class are the result of abnormal development of pluripotent cells: germ cells and embryonal cells.”

You can read a little more about the link between the teratoma and the parasitic twin below.

Fetus in fetu and fetiform teratoma

Fetus in fetu and fetiform teratoma are rare forms of mature teratoma that include one or more components resembling a malformed fetus. Both forms may contain or appear to contain complete organ systems, even major body parts such as torso or limbs. Fetus in fetu differs from fetiform teratoma in having an apparent spine and bilateral symmetry.[12]

Most authorities agree that fetiform teratomas are highly developed mature teratomas; the natural history of fetus in fetu is controversial.[12] There also may be a cultural difference, with fetiform teratoma being reported more often in ovarian teratomas (by gynecologists) and fetus in fetu being reported more often in retroperitoneal teratomas (by general surgeons). Fetus in fetu has often been interpreted as a fetus growing within its twin. As such, this interpretation assumes a special complication of twinning, one of several grouped under the term parasitic twin. In this regard, it is noteworthy that in many cases the fetus in fetu is reported to occupy a fluid-filled cyst within a mature teratoma.[13][14][15][16] Cysts within mature teratoma may have partially developed organ systems; reports include cases of partial cranial bones, long bones and a rudimentary beating heart.[17][18]

Regardless of whether fetus in fetu and fetiform teratoma are one entity or two, they are distinct from and not to be confused with ectopic pregnancy.

365 Days, 206 Bones, 1 Skeleton

This year I was looking for a 365 day project to challenge myself.  I almost chose 365 days of horror movies but though I might be a wreck after just a month, not to mention that some days I just couldn’t fit in a horror movie or find one to watch.  Horror movies isn’t much of a project either.  My partner always has good ideas and suggested I make a skeleton from felt. He didn’t think horror was a good idea as he doesn’t enjoy the genre.

I began the Skeleton around the start of the year with some sketches.  It’s already been a struggle getting the sizes right and finding references for parts.  Felt is a huge challenge with really tiny details as it is hard to cut small and make matching parts so small. I started with the hands and had to get creative with the scissors when my patterns were just too small to cut around. The bulk of the hands were done across about 4 hours but about another 2 or 3 hours needs to be added on top of that just sewing bits here and there and re-doing bits that went awry.

The Good Hand.  The second one worked out way better than the first.

Both hands.  One is very floppy (right) the other very stiff (left).

As I was making the phalanges I realised that making individual carpals was going to be bloody challenging as I would never get the sizes right so I decided to go with a solid piece under with details on top.  Artistic licence has come into play here as some parts were so tiny and the felt was not cooperating and I’ve heard that sometimes done is better that perfect.

All up I’m pretty happy with how they turned out but I think the stiff hand might need a re-sew. I plan to do the arms next.  Radius and Ulna.

Maybe I should try the horror thing out. Watch a month worth of Horror movies?  Maybe I could do a month of horror movies and TV shows (American Horror Story is in my Netflix list) and see how I go.

Heart Brooch

I’ve been playing around with designs lately and this is the most recent Heart.  I have a template for it that I haven’t yet lost (the last template for a nice heart went missing) and it is flat, so can ship at the cheaper postage rate, always a bonus!  I started making hearts like this when I was approached by a lady who wanted a gift for those who looked after her during heart surgery.

Treasures-Biological Drawings

I’ve been wanting to start a blog series about my most treasured possessions, so here it is, post one in the series.

My treasures fill my space.  Some are books, some things, some significant because of where they came from and what they mean.

I’ve had this book-Biological Drawings- for about 20 years.  The copy I have was published in 1957.  It is in fairly good condition considering it is a soft cardboard cover and has been kept in my room that tends to be filled with bugs who eat books, in fact it looks rather untouched by bugs. Perhaps it was covered in some sort of bug repellent many years ago.

Biological Drawings is one of my most favourite things.  Not only is it an old book but it is about anatomy of both plants and animals and was written by a woman.  I loved looking at the dissected rabbit when I was younger.  Recently I’ve most enjoyed the insects and the plants.

I love the little rabbit hands up near its head, all trapped by the removing of the skin.

Below, some of the plant drawings.

I was reading these bird beak descriptions to my cockatiel last night.

The only typewritten text is that on the cover, the inside cover and the index.  The rest is handwritten.  Another reason why I love it.

I cannot leave out this Rabbit brain!
