ok. if you have a favorite fitting anything - bra panties cane with
dog whatever
the local sewing shop has "pattern fabric" used to make patterns with.
take the favorite top. see where the parts are sewn together and lay
the "pattern fabric" on the parts
mark and cut.
now you have the pieces of your favorite top
you buy "coolmax" or better if its hot hot a mesh coolmax. Seattle
Fabrics has patterns that give yardage needed but I guess its 1.5
yards per top.
"coolmax" comes in white or whatever from Seattle Fabrics or Rose City
Textiles.
Sew the top(s) together with your mother's machine or by hand. snot a
big deal.
i don't know anything about the silk screen biz but poly is a tough
dye. Of the top of my head I guess the jerseys you see with Grateful
images or a dragon with IMA GOONA STICK IT IN YOUR
on the back are processed to take dye. fabrics without the IMA GOONA
on them may not be so processed.
Campmor's dayglo T's are 85% poly and 15% cotten (?) The cotten takes
the dye. Wal sold bright colors in poly witha bit of spandex or
something to take dye - that feels rubbery and is a less than hot
climate T fabric. That run was dyed in Lesotho where labor is cheap
and the EPA somewhat lax about pouring several extra thousand gallons
of used chemicals back into the ocean, chemicals necessary to get the
poly to "take" orange or yellow dye and come out bright.
Like the shop may take poly and say yeah yeah yeah we can do this and
yeah that and sure they will but the finished product may not be what
you had in mind when you wandered over there.
