I am looking for an internet site that sells CHILDREN'S size (ages 4-7
or the equivalent) LONG (elbow-length or just below) LIGHTWEIGHT
(satin or cotton) gloves, like a flower-girl would wear, but in a DARK
COLOR (preferably black--no pastels). My son has terrible eczema on
his wrists and the back of his hands in the winter, where his sleeves
rub. I bought long white satin flower-girl gloves and cut off the fingers
and thumb, and hemmed them. This works beautifully, but they get
terribly grubby. So I'm looking for the same sort of thing in black.

Hello, Atardiff.  Sorry to hear about your son, but I think your
creative solution is genius!  Here are a few sites to try:

http://www.somethingspecialbridal.com/gloves.htm
(scroll down about 1/2 to 2/3 of the way down the page, to "Children's
Gloves."  Although the pictures are white, they indicate that black
satin is available in elbow- and shoulder- length.)

http://www.costumesinabox.com/pd_childrens_elbow_length.cfm
and
http://www.costumesinabox.com/pd_childrens_shoulder_length.cfm

These are polyester, so they may not work, but just in case:

Scroll down about 3/4 of the way down the page, to "Child's Long
Gloves."  The picture is white, but the drop-down "Select Color" menu
includes black.  The direct link to the gloves themselves is
http://www.costumesinc.com/p1844/Childs-Long-Gloves.html?
However, it doesn't say what the material is.

And here's an Amazon link:

This one appears to be satin.

I hope these sites are helpful.  Let me know if I can provide any
further assistance.

Thanks a bunch. Just exactly what I asked for.

I am sorry to hear about your son's problem.

Maybe you could dye the gloves, or have them dyed.  Certainly if the
gloves are cotton, this would be no problem.  A flesh tone or a little
darker would probably hide the immediate dirt. (Hopefully, then, the
dye itself is not problematic.)

I am sure that you have informed yourself about exzema, but perhaps
this site adds some information:

After I asked the question (and got a perfect answer--thank you!) I
found out that what I invented by cutting up flower-girl gloves
already exists. It's called Posey skinsleeves. I re-invented the
wheel. But I don't care--I'm so happy to have found a solution to my
son's eczema. There are drugs that work, but they're all dangerous.
