I don't think you want tab top curtains - they are the type with a kind of squared loop on top that you slot a wooden pole through. You need tape top curtains, and most ready made curtains come in a maximum drop of 90". If you are looking for cheap curtains, IKEA do a longer drop, and a few of their styles have tape tops. They don't have a gret selection of ready made curtains, but on the other hand their range of curtain fabrics is quite good if you want to get some made. It's quite expensive to get curtains made, about €30 per width and a pair of curtains will probably be 4 x widths.
