Check out the papers already there and contribute your own papers!
The two websites contain detailed instructions on how to submit papers,
how to receive daily email announcements of new arrivals,
what journals accept the arxiv submission in place of a paper copy,
concerns about copyrights, etc.
Submissions should be tex files, in any dialect.
If you do not want people to see all the comments in your tex files,
save the following 3 lines into a file foo:
out = $0; n = index(out,"%"); if (n > 0) out = substr($0, 1, n);
gsub("YABADABADOO","\%",out); print out; }
after which you run in UNIX shell: awk -f foo yourtexfile.tex > newname.tex
After that submit your newname.tex file to arxiv.

Quilting - pictures of some of my
mathematics-related quilts. Check out the one about MSRI 2002/03.
Apparently the quilt got lost during its move back up the hill! Sigh!
For the last few years I have been developing
a very fast, efficient, and accurate method for making quilts.
I call it tube piecing:
it is to strip piecing as strip piecing is to traditional piecing.
I can make a quilt top with twelve rows of triangles,
each row having nine red triangles pointing one way
and nine yellow triangles pointing the other way,
all sewn together with 32 seams only!
I have many other impressive shortcuts.
At the end of October 2015,
my developing book has 440 pages.
The book contains many concrete examples,
but also mathematical formulas for changing sizes and angles.

Please let me know if you are interested in testing
Only standard quilting gadgets are needed
(rotary cutter and mat, sewing machine, iron, fabric, thread).

this information important).

My wish list:
Acrobat Reader: my favorite is version 5.0 (not 8.0, not 9.0),
because it has useful hidden features
(discovered by random and concerted strokes on my keyboard).
when I need to update a pdf file (that just got texed again),
I can do cmd-w to close the window, then cmd-left arrow, and this
brings up the same corner of the page as before,
with the same magnification.
But what about my wish list: I wish that 9.0 and later would do the same,
plus, it should position the window in the same corner of the screen
as I had it carefully positioned before, not in the center of the screen,
blocking out everything else.
