Washing fabric

Today I'm going to wash the yellow fabric for my bliaut and then I can start cutting. I have almost finished Maja's little red silk dress, I only need to attach the last side on the gold braid on one sleeve.
Apart from that we have moved some furniture in the big girls' room and packed away their big dolls which they haven't played with for years.

Yesterday I went shopping with my fried Anna and bought sewing stuff and a piece of shot dupioni to make a cap for Maja. m_nivalis has copied parts of Viking age head coverings from Dublin for me and I'm going to make a cap based on those finds.

Why should I buy purple velvet?

Could somebody please give me a reason to buy this lovely dull purple velvet that's on sale for ca 10$/metre (110 cm wide). It's the kind of purple that makes you understand why they used the same word for brown and purple sometimes in period. It's rather dark and in some lighting it could be taken for dark brown. But I don't know what to do with it and I'm not buying any fabric without a clear project in mind, not anymore. At least not velvet which can't be used for the earlier periods
