Can anyone tell me what backing to use when embroidering on ripstop please (I think that’s what it is. There are no clues as there are no labels in the jacket and I had not heard of this fabric before researching it on-line). I have been asked by my granddaughter to embroider a jacket which she purchased as a present for her friend. So far I have had to purchase 2 more to replace the one she gave me as when the embroidery is unpicked it leaves gaps in the fabric which are not always covered when re-embroidering because of the difficulty of getting the fabric back in the hoop accurately). I cannot get the fabric to lie flat. The ruckles round the embroidery are massive. I have been using tear away and also have tried using spray glue on the tear away but neither improves the final appearance.
