A 1-fold of is the graph obtained from a graph by identifying two nonadjacent vertices in having at least one common neighbor and reducing the resulting multiple edges to simple edges. A sequence of graphs , where is a 1-fold of for is called a uniform -folding if all the graphs in the sequence are singular or all of them are nonsingular. The largest for which there exists a uniform – folding of is called fold thickness of and it was first introduced in [Campeña, F. J. H.; Gervacio, S. V. On the fold thickness of graphs. Arab, J. Math. (Springer) 9 (2020), no. 2, 345–355]. In this paper, we determine fold thickness of , , cone graph and tadpole graph.
