here is part of what the Sticky says about transfers:
Buy transfers
Order on-line or check for coupons or sales.
Check with the DISigners to see who they use? (I use Amy-Mickey's Transfers). If you use poor quality transfers your shirts will run or look raggedy after a few washes.
If putting design on a white shirt - you can use either light or dark transfers. For any other color shirt - use dark transfers or else ALL white areas of the design will be the shirt color.
Dark transfers tend to have more vibrant colors and are more of a matte finish and light transfers are shinier.
The MINUTE that the printer flashes the "ink low" message, CHANGE THE INK CARTRIDGE. Do not try to get one more transfer out of that ink cartridge. (I did that and wasted a transfer because the transfer had vertical stripes through it!)
