Petrarchan #1.

At times, square words can make a wobbly fit  
in sonnets round-holed-ten-syllabled-lines,  
I find planes and spoke-shaves used on rhymes  
can shape them suckers up if used with wit.  
Chisels help, also sandpaper, fine grit,  
and one or two glasses of Rhenish wine,  
don't forget glue, a vice, butcher's strong twine  
to clamp all, as you fight to fit the bits...  
 
If your write takes on drab assumed languor  
take care to give your thumb a timely whack,  
the better to cure that lazy canker  
and put poetic passion, back on track!  
The assembling of these may well seem a chore,  
But soon, a cinch, like Ikea's flat-packs.
