Before I bind a quilt, I spray it heavily on both sides with water, using a garden sprayer. I then smooth it out on the floor and start pinning, using T-pins which are used in upholstery. I measure length and width and diagonally. If the diagonal measurements are the same, the quilt is square. I pin it about every 5 or 6 inches, just pulling it lightly in whatever direction it needs to be pulled. I let it dry thoroughly, at least 24 hours. Luckily my cats rarely walk on it when it's on the floor. The tearaway stabilizer I use is Ricky Tim's Stable Stuff which is polyester and it will soften and slightly pull apart when wet, so it doesn't matter that pieces are left in the stitching. Ricky Tim's video, Grand Finale, has a part in it on blocking. That whole video is worth watching. I don't wash my quilts in a washing machine because I don't like the idea of squishing them up to put in the washer. I think wetting them as much as I do gets the starch out sufficiently. I will say that if you have berber carpet or a place with commercial carpet it is easier to block. I used to work at a frame shop that had commercial carpet where I could block after hours. I no longer work there so I have to block on my somewhat plush carpet, which can be done, but is a little bit of a challenge. It is, however, worth the effort.
