Based on the fact that everyone has their own recommended approach, I’m pretty sure there isn’t a right or wrong way to prepare quilting fabric. I routinely wash it but I don’t starch and I don’t use fabric softener. Quilting fabric goes in with the family laundry, with a colour catcher added if I feel there’s a risk of dye running.
I pre-wash batts, too. I put them in my front-loader on a wool cycle, with no laundry detergent and they hold together just fine. I prefer a smooth quilt over a puckered one and I don’t generally re-wash before gifting or using the quilt, so it’s good to have all the washing out of the way up front.
The clothes airer works brilliantly for drying the jelly roll strips. I wouldn’t dream of using the drier for them – way too much wear and tear. I suspect I wouldn’t have any fabric left to sew if I used the drier. The strips do get a bit hairy in the washing machine, but I can live with that.The cutting for this quilt was a little tedious. The hard part was making sure to cut trapezoids for the lighter shades and reverse trapezoids for the darker shades. From time to time I got that part wrong and I’m going to argue it was deliberate, to break up the colours a bit and add visual interest. Other than that, you line up your Omnigrid 96L, using the 2 1/2 and the 5 inch lines as references and cut away. There’s not much room for error as you don’t get a whole lot of fabric left over at the end of each strip. If I really had to re-cut a trapezoid I could probably find a scrap long enough, but I’d have to audition a few off-cuts before I did.
