1928 was a year of change in Girl Scouting. The familiar khaki uniform was replaced by the newly restyled, updated green uniform. Although considered green, the fabric was actually a mix of white and greyish threads, creating a grey-green color.
 
As stock of khaki badges were sold out, new badges were produced on the same grey-green fabric. Originally the badges were on  squares of fabric, to be trimmed in tucked when stitched to the sleeve or the newly launched badge sash. Later the badges were cut round with the excess fabric still needing to be tucked under.
 
As always, badge requirements and designs were constantly updated to meet the needs of Girl Scouts. In 1935 the newer silver-green fabric was introduced for badges, so popular badges may be found in the new fabric prior to the 1939 launch of the new uniform.
