what i`ve got is not as thick as blanket, but if i lanolise it (and hotwash it first?) then it might be alright. Last night I was browsing and found how to make the same style as the Disana covers out of old jumpers! Quite cool, but the person who made them said that their kid never wore trousers since they made them - cause of their bulk. Which didnt bother them, but might bother me.
As far as using the Disana tie nappy- if I go with them, I dont know if a neat fitting wrap cover will fit properly over them. And I would prefere not to have anything too bulky as even with the kooshies I used with ds, some baby clothes wouldnt fit over them.

I managed to score small stack of lovely new merino from a designer clothes shop that was closing for only a few $. Not pretty or funky colours, but nice to have the natural fabric. I wish I`d thought/known about needing nappies before I gave some of it away!
