Colin, Dave and Ray,
Many thanks for all your suggestions.
Colin, I`ll give Hobbycraft a miss regarding the balsa. Ray also suggested styrafoam block and sheet so that will be worth a look as well. I need to wait till the plan arrives to see the best size to get in which ever material, A continuing learning curve for me.
Dave, thankyou for your help. I`ve not tried any of the De Luxe adhesives yet but have used some of their other products and found them excellent, ( on the model railway side ). On Gorilla glues, they do a waterproof one which is good but you have to make sure you wipe off any excess as it expands while drying and then could give you problems.
Ray, Thanks for posting that side shot of the Cigarette. You`ve shown what I thought wasn`t quite right with mine in that I need to make the white discs bigger. The lettering I traced off your plan using greaseproof paper , but I need to have another go using, as you suggested, card. My greasproof paper tracing out wasn`t too bad but on a test try, it bled out with no sharp edge. I`ve a good selection of brushes but I think I need a really small fine point to get the lettering decent. I`d be pleased if I got somewhere near what you managed.
Regards, Jim.
