I have two denim quilts "in progress" one fray edge and a highly experimental foundation pieced effort, using strip and crazy techniques. The fray edge will be backed with flannel and I am toying with the idea of using lightweight fleece as a middle to the sandwich...the other one is just "evolving" and I am thinking of using an assortment of "recycled" cotton fabrics for the back and tying the quilt using felted discs as a design element.
Just a couple of things I learned along the way....save the tops, you can make bags out of them....a couple of pockets cut out and put on the quilt are a good place for phones,games and other "treasures" to be stored...don't use overly worn or stained sections...don't use jeans containing elastane (it curls and is just not user friendly). Handsewing denim is really hard work, give machining a try and a denim needle is a must have...it really makes an easier job of it.
The Pilgrim photo is brilliant....I am in danger of becoming the female equivalent....the spiritual aspect being somewhat different...I am just a fervent hunter and collector of fabrics and recyclable treasures...No charity shop or car boot sale is safe from this woman's mission!
