Here's what you'll need:
blocking pins - We recommend Clover's flower head pins because they are sturdy, rust-proof, and cute
spray bottle - Any spray bottle will do as long as it is clean. We love this old copper gardener's sprayer.
towel - Choose a towel that is big enough to fit your knitted pieces, and not too linty.
soft surface - You can use your ironing board for small projects, or your bedspread, the carpet, or a fabric covered couch cushion for larger projects. You'll be sticking pins into the towel on top of this surface, so choose something that won't mind getting a few stray pin pricks.
To make a portable blocking board, cover a 18 x 24-inch piece of 1/2-inch plywood or MDF with cotton batting. Staple it to the back using an upholstery stapler. Cover the batting with cotton fabric, attached with velcro so you can remove it for washing after a while.
