Rounding the corners prevents the corners from fraying and/or lifting.

We recommend 3 minutes as absolute minimum. The adhesive needs to set and 3 minutes may not be enough.

We advise still cleaning the area for the patch. The patch may stick on BUT will not last to your or our satisfaction.

Provided your blanket has been stored in a dust proof bag, sponge the area to be patched then let it dry.

Yes, absolutely! We have done the same, over 100 washes and counting!
