Warning about flannel- prewash it Before cutting due to shrinkage. It can get rough so find a non-pilling brand. I wash baby quilts in hypoallergenic detergents and don't use dryer sheets if the fabrics haven't been prewashed this way before assembly. Also- if using fleece or Minky be aware some don't stand up to high heat by melting a bit and becoming scratchy so label it for cool or low dryer temps. I make either rail fence or I spy. For the I spy I use 6 1/2" (unfinished) squares alternating with 6 1/2" 4 patches made from 3 1/2 " strips. Just as easy with a single focus fabric. On Maryquilts.com
http://www.maryquilts.com/quick-strippie/ I found a super simple free quilt pattern called Quick Strippy. It's very fast to sew- made simply with horizontal strips- no intersections to match up. I've made this with beginning quilters- great confidence booster.
