You can use to glue your petals egg white or a gum made with 1 part of cmc and 20 parts of water. it is better to use warm water to dissolve it, next day will be without lumps.
Freshly made gumpaste obviously won't be dry & just kneading it will make it pliable enough to use but bought gumpaste,when you don't know how fresh it is,won't become pliabe just sitting there - you have to knead it really well and if it is too dry to use then yes, add water and/or shortening to it to get it soft,elastic . You can use water to stick your petals together before they dry,otherwise use the glue bananabread mentioned or eggwhite.
