I copied and pasted the search for the Plaid set at Hancock Fabrics and couldn't find it there.
What I am looking for are the tips (can be either metal or plastic, but preferably with a cover) that will fit directly on an Elmer's glue bottle so I don't have to fill a little bottle with glue. I think these are the tips that are so hard to find. Susan Schamber's daughter's website (Purple Daisies) used to sell metal tips, and more recently sold a pair of plastic tips, but they all appear to be no longer available.
