If you already know the 4 digit color number for the threads you want, please enter them in the block provided. Enter the color numbers from left to right and please put a space between the color numbers. The price will NOT be calculated by the website - we'll do that calculation manually and make sure we use the volume pricing for the quantity you order. The $15.00 shown as the price for these threads is not correct. You will be charged $4.80 for each Sulky Blendables spool.
