No prob, maybe this will help:
The embrodiery hoop looks like this:
You can buy it REAL cheap at
Walmart, it's only a couple dollars, and they come in various sizes, so basicly get the size you want the autograph to fit in (not too much bigger, cause the bigger the hoop the "looser" the fabric will be and so harder for the characters to use)
It consists of 2 hoops, one inside the other. Just loosen the screw on the outside one and they come apart:
Then just stretch whatever you're using over the inside hoop and put the outside hoop over it and tighten the screw and vwala!
Just make sure your fabric is nice and tight so it makes a nice, smooth, "hard" writing surface for our friends!
I know it probably sounds all complicated for just an autograph, but I think it works better than just putting the shirt on a table or something, cause then the fabric can "snag" and when you're out about in the parks it can be hard to find something flat to put fabric on to sign, and I have heard of characters refusing to sign anything someone is wearing.
So, this way I just know I am all set to go and can just whip it out for the character to sign, as quick and easy as any autograph book.
And then my kids have a wearable memory, or something to lay their head on and dream of Disney.
