Please consider the situation:
A bread piece has some tiny particles which we see keep on removing off bread, or lying loosely on a surface after we remove it from that surface (These tiny particles are called 'bread crumbs').
Suppose I have to say a sentence for a biscuit piece/bread piece, such as:
"Don't put these biscuits/cookies/bread pieces directly on bed sheet as it will/it is _________. Better put it on a plate and then eat."
Please suggest a word/phrase in a context related to a process of removal of something (such as tiny particles falling apart off a biscuit, or a bread piece).
The word 'crumbs' can be used here, but I am not able to fit it here.
I am unable to find a proper way to frame this sentence. Please suggest any other way to interpret this situation.
