I've let it be known before that I rarely knit "trendy" items...but as a professional knitter now, sometimes I get asked to. In August I got a request for a pair of slippers. Pretty simple, she even supplied me with a photo of what style she wanted (for her husband). It's the old standard slipper pattern that anyone who has been to a church bazaar at Christmas time has seen. The pattern I located is called "Aunt Maggie's Slippers".
At first, she picked out a colour scheme, but then she found a Bernat boucle yarn online that she liked, but I couldn't find it in the store. She wanted a blue and grey slipper, with some wool content. I ended up with LionBrand "Homespun" and "WoolSpun". I think I used 5.5mm or 6mm. I didn't want to flatten the Homespun too much with too small of needle, but they still needed to be knit dense for warmth and longevity.
