Hi Dawn,
If I have understood your description correctly you will be using original fabric in the form of offcuts so there should be no infringement of the any copyright which may exist in the print on the fabric since you are not copying.
Assuming the design of your toys when covered by this fabric does not copy the design of similar toys made by or on behalf of the owner of the copyright in the print (this would need to be a registered design, so it is easy to
check this on the Intellectual Property Office website) then that shouldn't be a problem.
Finally you need to
check (again on the IPO website) that none of the fabric designs are registered as trade marks. This seems highly unlikely and apart from the ones which incorporate words (if I have have understood that bit correctly) it will be quite difficult to search the figurative marks database. I suggest you limit your search to
classes 24 (textiles and articles made with textiles) and 28 (games and toys).
If you have any full widths of the fabric which include the
selvedge (the part where the printing machine grips the fabric during manufacture) this is the most likely place to find any information about registered designs or trade marks, along with the manufacturer's details.
