So I have to reveal first, I'm not a pet owner or a prewasher of fabric. I ordered fabric off etsy and yes I loved it to pay 15.00 for a yard with shipping... I got it and it's black fabric covered in white cat fur.....really???? Seriously??? ...end rant. Now I never prewash fabric, 5 kids I have enough laundry! I have to prewash this, am I going to have a huge issue using it with non prewashed fabrics? Or should I keep it in it's envelope and wait til I have all the fabrics in mind for this project and prewash this whole project? Which is going to be the less aggravation??? Thanks, Rachel
