I don't currently subscribe to any.
I used to love QNM (quilters newsletter magazine) but the patterns it offers currently are like every other magazine IMHO.
I prefer the older issues (pre-2005) of magazines, generally speaking. That's before they started selling "easy" and "fast". Quiltmaker was one I liked years ago but I find it boring nowadays.
Individual issues are expensive so unless one really hits me or it's the Quilt Sampler (Top Shops), I don't buy them.
