Note that Dalgleish no longer is selling direct to non-trade customers. You'll need to place your order through one of their trade customers, such as Scotweb, or here in the US, ourselves. They can do a short length no problem.

The reason I did not reply to this thread sooner is that your OP stated you were looking for PV or acrylic. Dalgleish will do wool or silk. If you want either of those options, more info can be found here:
