I was born in 74, so I’m guessing this book was published in the late 70’s to early 80’s. It was illustrated, soft cover. Full of instructions of how to make a variety of paper airplanes…how to make a little windmill…how to prepare fun snacks (with Mom and Dad’s help in the kitchen of course).
But what I remember the most was the motif of funny little pigs holding up signs with letters of the alphabet. The pigs and signs were used to spell things throughout the book, from the front cover to chapter titles. The pigs were constantly up to mischief and richly illustrated. You had to slowly pour over them to see all of their little quirks. They would sometimes have problems arranging their letter signs into actual words.
I got hours of enjoyment out of this book when I was a kid, but I can’t find anything about it with Google. 
I think we might still have it somewhere back at the homestead with my Mom. If my fellow dopers can’t help me fill in the blanks, I’ll pester her to clean out a bookshelf or too.
