Hello, I'm working on my first project, a baby blanket of knitted squares crocheted together. Most of my yarn is the same brand & manufacturer, but I want to use a different brand for the edges, and possibly some of the squares, and I'm wondering if that's likely to be a problem. The squares are 20% wool/80% acrylic; the other stuff is 100% acrylic, but has similar thickness and washing instructions.
Are the yarns likely to stretch/shrink at different rates? Enough to ruin the project? I'm assuming not, but I've heard about making assumptions...
Is mixing yarns ok for a baby blanket, but a bad idea for (i.e.) a sweater?
Thanks for the help!
