Where can I get strong velcro from ?

[poppy101]

Wheres the best place online pref. to get really strong velcro from that I can use on my lo blackout curtains as they do not really work.
Any ideas where I can get it from ??

John Lewis or a market stall, I know it sounds daft but have you tried both.

Also have you thought about taking off the velcro/sticky stuff and simply sewing them onto your curtains at the top hem with a quick hemming stitch (hope this is the right stitch). If you do it at the strip at the top you won't know the difference.
