hashashan: I thing, that high temperature like in oven is not so good, because my expiriences showed, that hemis was deformed more than in normal room temperature. Dextrin is easy for dry, I tried wheat starch, wheat flour, white glue, paper glue, sodium silicate solution and no one from this isnīt convenient like dextrin, dextrine is perfect.
Bye.

The program itself is working ok, but Iīve got one question:

Iīve used a plastiv halve with a radius of 49mm. I used your program,
typed in 49 as "r", used 6 leaves and 300 DPI.
The image the program created was 1818*1818px in size.

Now my question: What size to print it? I used 98mmē but that
filled just about the half of the hemi...
Here are some pix:

Any help appreciated :P I printed it 149mmē as well. that way it fits into the hemi neatly...

Install IrfanView, open shell image and type " i ", next change DPI :)

SCREEN

Next save file and print... And check... I can't check this file, so I wait for your opinion :D

Hey Sensei! I changed the DPI to 300 in Xnview (used to that program! :D ) and oh wonder! Printsize automatically changes to the proper
value of 15.392cm!

Big thx. Now I like that program!


A few things to add, anyway:

1) You could add "cm" next to the value field and a checkbox "use inch" for our american friends :P
2) a note like "Change DPI to 300, when printing it" could help to avoid dumbs like me asking
for that! :D
3) The paper gets very "fragile" when you cut it too far (which is easily done when using that pattern) So a pattern with a bit longer
lines from the inside would be nice. Hope you know what I mean :)


Anywa: Nice program!

Passfire is a great site, well worth the admission fee

Do your hemis change size over time?

try making hekis using cellouse fiber mixed with kitter litter in powder form roll out the thickness you want let it fall over a 2 or 3 inch rubber ball work it all the way around the ball.Its easy cheap and fast once you keep doing it I have avid of it
