I love solids and have a sizable stash of them. I think my favorite pure solids (i.e. not shot cottons) are those from Free Spirit as they have a wonderful sheen and a very soft and luxurious textures. And normally I would say this is followed closely by Kona solids but they might be pushed into third place now by 'Cotton Couture' as they too have a fantastic texture and are very light. Of course the biggest selection of colours is provided by Kona so they will always rank pretty high with me and will most often be the first choice simply because of their wider availability.
