An optional overlay mosaic technique to help "tack down" long flaps of sc on the back of your overlay mosaic blankets. This doesn't personally bother me at all - but I thought I'd share the option!
Fair warning - If used for the ENTIRE blanket (not just here and there to tack down long rows of sc on the back) it will squish up the blanket, not in a bad way for the design - but it will cause the border to ripple a bit on the sides. I discovered this when making the tapestry overlay mosaic version of my "First Coffee...Then Things" blanket pattern.
