I purchased the plugs suggested for my 21"doll but the arm ones are to large any suggestions.
Warm the vinyl and they should go in.
I do not use plugs, You can cover with moleskin if you just want something to cover them with.
I’ve had this happen and used a different size plug. Each time I order, I add in plugs and eyes of various sizes so I can use different sizes when needed.
If the plug is just a little too big, you can also use a craft knife to trim off a little of the inside rim of the flange so it fits.
