A homemade kite seems to provoke comments:

"Your homemade kite looks like a copy of a (Fill in the blank)"
No it's a copy of the kite the (Fill in the blank) is a copy of.
"Those plans on the Web are not good enough to sell."
Yes, they really suck big-time.
"You'd be a better flier if you went and bought a real kite."
I'd still be a klutz. 
"By the time you buy a sewing machine, fabric, spars, fittings, a kite will cost a fortune."
Buy Pfaff, make kite, discard Pfaff. I get it now...
"Copying someone else's design is theft."
My life of crime started with a newspaper Eddy, and led to harder kites.  Soon I was
one-lining Codys. Stop me before I stitch again!

"But look at how shaky this seam is. My (Fill in the blank) has perfect....."
I sneezed (or something) while sewing.
"What the hell is that? Hah! Never heard of it."
Not surprising.
"You are better off just buying what you want in the first place."
But then I couldn't enjoy making it.
"Who wants to waste all that time trying to make a kite?"
Well, Survivor was a re-run, so..."

While trying out your kite, here it comes...

"Not too bad."
So it's simply bad enough?
"It pulls to the left a bit."
I pull to the right, so it balances out.
"Something's not right with the bridle.  What does it need?  I dunno..."
Thanks for the tip.
"It sure doesn't fly like a (Fill in the blank)"
Because it's not a (Fill in the blank)
"It would be better with lighter, stiffer spars."
Me too!
"You should try my (Fill in the blank), and you'll see what I mean."
Do I have to?
"Have you seen the new (Fill in the blank)?"
No, I haven't been to a movie in a while.

Thanks, I feel better now.

They're only toys.
