Hello
Well done for trying
@morning glory Gf flour does not like being handled so possibly you worked it too much? Having low expectations works well too

It really does not work well. The ready-made jus-rol is awful! (hard, thin and tasteless). The best GF pastry I have made was tasty but crumbly so could not be picked up like a sausage roll.
I agree with
@ElizabethB that the gluten free fad is unnecessary, and also very unhelpful to those who do have an allergy or are coeliac. The fad makes it difficult because people assume you 'just leave out the bread' but don't realise that a roast dinner is fine but hold the Yorkshire pud and the gravy thickened with wheat flour (someone with a gf fad may leave the yorkie but not think about the gravy), or chips are fine but not if cooked in the same oil as battered fish. Products are very expensive and full of sugar, but I think this is similar to all ready-made food. I tend to cook everything myself, but my breadmaking is not that great and I don't have room for a bread-maker (a friend has one and is coeliac so is experimenting for us both!). We can't use gluten free oats (see below) but do buy tamari instead of soy sauce and I buy gf flour and baking powder (and check dried yeast as some contain wheat flour). Stock is another thing I need to check if buying, though I find there are brands that are GF and a lot cheaper than the GF branded versions.
My husband is not coeliac but has an allergy. Foods classed as gluten free have fewer than 20 parts per million. This is useful for those who are coeliac but is too much gluten for someone with an allergy.
My husband has conditions called trigeminal neuralgia and temporomandibular jaw syndrome. He has typical and atypical which means he is in constant pain but also gets short term extreme pain that is often called 'suicide syndrome' (because people do!). Gluten causes swelling that pressures the nerves and joints in his face, so this means we can control, to a point, this issue.
I can no longer have gluten in the house. Even if I sneak in a bread roll, the crumbs and loose flour will affect him. If I want to cook with gluten I have to go to my parents.
Give it another go
@morning glory If you do give up then use the flour to make a crumble , pancake or cake as the GF flour works well with those where the 'holdability' is not required.
