Thunderbird supply had patterned sheet as of 2006,Santa Fe Jewelers
supply sells patterned low rich brass sheet,H.Schmidt has it but by
special order ans in gold above 10kt only, but if you have a rolling
mill with the capacity for interchangeable rollers then Rosenthal
Supply has a vast array of patterned sheet and wire rollers
relatively inexpensive in cost. If you're adventurous reactive metals
has some interesting products to texture,pattern,carve and colour (
in your case though sounds like their bi-metals may be the thing
closest to what you were used to..and are not actually embossed
sheeets though the versatility and unique patterns you can achieve
are heir line mat give a new dimension to your work), the first two
definitely have traditionally patterned sheets that are brass,and
copper and sometimes in silver
