Our preferred methods of serving you…

First choice – complete the order form and simply click submit! Remember, if you have any questions; please just give us a call.

Second choice – download our pdf order form, print, scan and email (or print and mail). This is equivalent to completing the online order form (first choice) and is meant for those who simply still like sealing a real envelope and affixing a stamp.

Third choice – Prepare a paper pattern (also known as a paper rubbing), along with sample original strings and send to us. Click here to learn how to make a suitable paper pattern.

Fourth choice – Remove all original strings taking pain-staking care they remain in perfect sequence, package and send our way. The end result using this method is that you will incur the greatest expenses and receive the least accurate set of new strings. Regarding the 'fit' of the new strings, they will only be as good as the originals (i.e. how far from the bridge the winding begins and how far from the agraffes the winding begins, and how even these distances are throughout the whole set).
