There's a recent Macworld article for quickly making Stickies. I thought that some folks might want to make Sticky Widgets instead.
This is derived from my hint posted a few years ago.
Depending on your system version (and possibly other factors), you may need to launch Dashboard at least once if you haven't since system startup before trying the Service.
Here are the simple steps:
activate
set inputText to (input as text)
do shell script "open /Library/Widgets/Stickies.wdgt"
delay 0.2
tell application "System Events"
keystroke tab
keystroke tab
keystroke inputText
end tell
