I posted this on the Posie thread (and elsewhere) but one of the things that happened after it became more normal (though not reliable) to get funding for refuges many women who have been supportive in a local way sort of stepped back. Not because they thought they didn't have the skills, but an assumption that funding would cover everything.
In fact the intial funding wasn't funding at all, but an agreement that women in refuges could claim housing benefit (this is why historically refuge funding always came under housing and it was only years later that the concept of funding for women specifically in response to male violence happened - partly because men didn't want it to be acknowledged that there was such a problem).
But many refuges only survive through local support. And in fact if refues hadn't been left isolated and coming under pressure from funders' priorities, we may not (perhaps) have landed up with the refuges being told single sex services weren't a priority.
If you check with you local refuge, particularly at christmas they will post a list of items they would like donated, or may have an amazon wish list.
But as with appeals for refugees (whether in camps or without settled status) and in fact what happened after Grenfell, donating old clothes etc., my seem like a generous thing to do, but can add to the sense of being dislocated from your own live wearing someone else's hand me downs. Far better to have a jumble / car boot sale and give money. Or sets of underwear or whatever.
Whether as an informal network of friends or an actual support group this seems like such a positive thing to be doing.
Just in case anyone thinks I am dismissing what OP has talked about, I am saying this is such a great example of how it is possible to support women as volunteers and as paid "professionals".
An in an ideal world would be great to do this in cooperative way.
